Instalasi Jaringan P2P

Posted in Work-with Love with tags , on March 11, 2009 by Paulus Bayu

Banyak perusahaan sekarang ini membutuhkan jaringan lokal yang terhubung melalui media nirkabel (wireless). Kebutuhan transfer data antar cabang dalam satu kota dapat lebih efisien dengan mempergunakan perangkat radio yang khusus dipergunakan untuk mengirim dan terima data melalui protokol TCP/IP. Pada masing – masing titik terpasang satu set radio dengan frequency 2,4 mhz atau 5,8 mhz.

Dari beberapa pengalaman melakukan instalasi jaringan wireless dengan protokol point to point terdapat beberapa kelebihan :

- Sinyal TX dan RX relatif lebih stabil dibandingkan dengan multipoint protokol

- Kapasitas troughput yang didapat juga lebih besar dibandingan dengan multipoint protokol

Bagi anda yang membutuhkan konsultasi masalah pembuatan jaringan wireless dan pemasangannya dengan senang hati saya akan membantu dan mencoba mencarikan solusi yang terbaik buat anda.

How to Tweak Windows XP for Optimal Performance

Posted in Know-How on February 2, 2009 by Paulus Bayu

The purpose of this guide is to tweak Windows XP for optimal performance, get rid of all the useless extras that Windows XP comes with, and to decrease the startup time of Windows XP.

:: Test System
Pentium II 350MHz
128MB RAM
2GB Maxtor Hard Drive
8x Mitsumi CD-ROM
100MB NIC

This system is a peice of crap by today’s standards, but after I tweak the install of Window XP on this system it will run faster, use less RAM, and boot up times will be lowered.

For comparison at the end of this guide I recorded the boot up times of Windows XP right after a default install.

Boot up (time to get to logon screen) = 59 Seconds
RAM used at startup = 60 MB
Processes = 15
Time to load after logging in = 35 Seconds

1A. Disabling Windows Themes, transition effects, and smoothing fonts

One thing you’ll notice if your upgrading from an older version of Windows is that the start menu and all the windows now have this Bluish theme. Since this is a tweaking guide we’re going to get rid of this bluish theme to save RAM. First thing you’ll want to do is right click anywhere on the desktop. It’ll come up with a menu, click on properties and a window will come up called display properties.

Themes, Select Windows Classice from the slide down menu –> apply.

Desktop, select none from the list of background –> apply.

Screensaver, select none from the drop down list of screen savers –> apply.

Appearance, go down and select “effects”, a new screen will pop up, unselect everything including transition effect and smoothing of fonts –> ok –> apply.

Settings, don’t need to do anything

1B. Customizing the appearance of the start menu and task bar

Right click anywhere on the task bar, a menu will pop up, select properties.

A. Task Menu

Task appearance, customize this to your liking.

Notification area, customize this to your liking.

B. Start Menu

Start menu, this is the XP default start menu leave it if you like it.

Classic start menu, this is the older version of the start menu found in older OS’s like Windows 2000 or Windows 98, if you perfer this start menu select it and apply. Once applied, Windows will dump the My Computer, Recycle Bin, etc… icons onto the desktop.

C. Select which menu you want, either default or classic, and to the left is the customize button. A new pop up window will come up for either one and customize the look of the start menu to your liking.

2. Gaining performance through system properties

2A. “Advanced” tab in they system properties window

The first three tabs in system properties you won’t need to change, but the third tab called “Advanced” you will. There are some options here you can disable to improve performance. In this tab you’ll notice five things you can select: performance, user profiles, start up an recovery, enviromental variables, and error reporting.

A. Select the settings button for the “performance” section and click on the “adjust for best performance option” –> apply –> ok.

B. Select the “Error Reporting” button. Next, select the “diable error reporting” option and uncheck the “but notify me when critical errors” box.

C. The “Remote” tab, uncheck the “Allow Remote Invatations” button, You’ll want to turn this feature off for security reasons. If you actually use this feature leave it on.

D. Automatic Updates Tab, Select “Turn off Automatic Updates” option and proceed to next tab.

E. System Restore, You’ll want to select the “Turn off System Restore” option. I think this feature is a complete waste of system resources, but for you paranoid psychos out there who think their computer could die at any minute then you can leave this on. Otherwise turn it OFF! It will give you a warning message when you disable it, just click yes when it comes up.

3. Increasing file system browsing

Another thing XP has changed is the way the folder icons look. It used to be small icons for the all the drives and the controll panel now it’s made up of rather large icons that consume their fair share of the system resources.

3A. To prevent the large icons from taking up too much system resources start by clicking on the view button –> list

3B. Next click on the view button again –> status bar.

3C. Double click on my computer, a window will pop up, at the top of the window click on the tools button –> folder options.

A. General tab, you won’t need to do anything here.

B. View tab, it’s comprised of two sections, folder view and advanced settings. In the advanced sections area start by making sure you have the same settings as listed below,

:: Folder Options
Uncheck – Automatically search for network folders and printers
Uncheck – Display file size information in folder tips
Uncheck – Display simple folder view of Explorer’s Folders list
Check – Display the contens of system folders
Check – Display the full path in the address bar
Check – Display the full path in the title bar
Check – Do not cache thumbnails
Check – Show hidden files and folders
Uncheck – Hide extensions for know file types
Check – Hide protected operating system files (Recommended)
Uncheck – Launch folder windows in a seperate process
Uncheck – Remember each folder’s view settings
Uncheck – Restore previous folder windows at logon
Check – Show control panel in My Computer
Check – SHow encrypted or compressed NTFS files in color
Uncheck – Show pop-up description for folder and desktop items
Check – Use simple file sharing

After you’re done checking and unchecking all of of those options, click on apply button at the bottom of the window, then at the top. Click on the “Apply to All Folders” button to apply the same settings to ALL windows folders. Click on the X to close the window. You won’t need to do anything else on the other tabs.

Now browsing through the Windows file system should be immensely faster.

4. Getting rid of all the extra programs Windows XP installs

4A. Double click on My computer –> control panel –> Add/remove Programs. To the left of the Add/remove Programs window there are three options, choose the last one “Add/Remove Windows Components”

Once the Windows Components Wizard window pops up start unchecking everything except Internet Explorer and Update Root Certificates. When you unselect MSN Exploer it will give you a warning message, just ignore it and click yes. There are some small programs in “Accessories” like calculator, paint, and the games that come with XP. If you need any of them click on “Accessories” then click on “Details” and check and uncheck the ones you need. When you are done with all this exit back to the Wizard and click next. When it’s done, click on finished.

5. Windows Services

One of the most crucial components of Windows. In this section of the guide we’ll disable unnecessary servies. I really don’t want to explain what each and every service does as it would take quite some time. If you curious here’s a link to a fantastic website that’s all about Windows services and what each service does, click here. What I’m going to do is list all the services you can safely disable without worrying it’ll screw up windows, all the services you should leave at manual, and the services you should always leave at automatic.

A. First of all right click on the My Computer icon and click on Manage, a new window will pop up on the left is the menu, go down click on the plus for “Services and Application” to expand the menu. Last, click on the little icon with the gears named services.

B. To disable a service right click on it’s name –> properties. I new window will pop up and with a description of the service, startup type roll down menu, and buttons to stop/start/ pause/resume. Simply select “disable” from the “start up type” menu to disable a service.

*1 = If you only have one computer in your network you can leave this service disabled. If you have more than one computer in your network, at least ONE of the computers in your network must be running this service in order for computers to show up when you go into My Network Places –> Entire Network –> Microsoft Windows Network –> Name of workgroup.

*1b = Needed for verifying updates downloaded from Microsoft (Windows Update, DirectX, Service Packs, etc…)

*2 = If you’re using DHCP in your network, leave this service at Automatic.

*3 = If you have more that one person (e.g. family computer) using the computer you’ll be tweaking leave this service on automatic.

*4 = Need lots of help? Leave this service on automatic instead of disabled.

*5 = Leave this service on automatic if you like XP’s integrated CD burning feature.

*6 = Leave on automatic if you use ICS to share a connection with other computers on your network

*7 = Have a printer? If you do leave this service on automatic or else you won’t be able to use your printer at all.

*8 = If you have a removable device in your computer leave this service on automatic.

*9 = Use Smartcards? If so leave both on automatic?

*10 = The psychotic paranoid type who thinks his/her computer is going to die at any minute people should leave this service on automatic.

*11 = If you use Remote Desktop leave at Automatic.

*12 = Leave at automatic if you use a UPS.

*13 = If you have a scanner attached to the computer and use it, leave at automatic

6. Restart!

Finally after doing all this tweaking you should restart and see how much faster it goes! Another thing I want to mention is to always defrag reguarly or else performance will slowly degrade.

7. New start up times

:: Before
Boot up (time to get to logon screen) = 59 Seconds
RAM used at startup = 60MB
Processes = 15
Time to load after logging in = 35 Seconds
:: After
Boot up (time to get to logon screen) = 52 Seconds
RAM used at startup = 42MB
Processes = 12
Time to load after logging in = 15 Seconds

The results may not seem very impressive, but this IS on a very outdated machines. Your results will differ depending on how fast your machine is. After tweaking XP on my main rig the startup time went from one minute to get to the logon screen to a mere 20 seconds!

8. Last Words

If you don’t want MSN Messanger to start at startup simply logon to your accout and go to tools –> options to disable it. If you don’t have an account, as it won’t let you change the options without first logoning on to an account. Click on the Start Button –> run and type in “regedit”, then go to,

HKEY_CURRENT_USER\Software\Microsoft\Windows\Currentversion\Run

Delete the key that says,

MSMSGS – REG_SZ – “C:\Program Files\Messenger\msmsgs.exe” /background

And Another thing, if you’re the only person that uses the computer you can easily disable the fast user switching feature by going to My Computer –> Control Panel –> User Accounts

A new windows will pop up, on the menu to the left click on “Change the way users log on and off” and finally, unselect the “use welcome screen” option –> apply option

9. Conclusion

I hope this guide helped you out and made your computer just a little faster. Because Windows XP comes with so many useless things you can easily disable them to increase performance. The performance isn’t with a price though. There won’t be any “eye candy”, fading folders or menus, previews of pictures and mp3’s, and no more Windows Themes. In other words it won’t look nice and pretty with all the effects turned off, but it won’t really matter once you realize just how much faster things are!
