Very slow performance

By Shanghai Sam ·
I have a laptop with windows 2000 professional installed. Lately the Operating System has been running really slow and the hard drive is thrashing quite a lot. I took the following steps trying to make it faster:
1-) I removed the page file from C and redistribute it among the three partitions I have (C,D and E). I made the page file 1.5 times the size of the total ram (512 Mb of RA) I made the size equal minimum and maximun.
2-) I cleaned up the hard disk drive
3-) disk defag and still is running slow.
4-) There is enough space in C for paging.
So far I have not been able to figure out what may be the reason of machine running so slow. Takes forever to open apps but the name resolution is good and the browsing service is runningcorrectly.
I am runnig Zone Alarm. My questions is what else can I do to make this machine to run faster.
Is there a possibility that there is a hardware failure?
or maybe a virus infection???
Need help. As usual, this machine belongs to the company owner.

Try ctrl-alt-del, click on task manager, click on the processes tab, on the bottom it will state the number of processes running CPU usage and memory usage, from what you describe i suspect you will see the cpu usage to be running over 80% if not 100%. Click on a running process and then click on end process until you see which process is using up most up the cpu time, once you determine what that process is then you can deal with the problem

Very slow performance

I feel that 750MB is much too small for the paging file.

I use a seperate partition (to avoid fragmentation) of around 2GB. Even then, Windows sometimes runs out of room.

2 things to do;
1. Disable the paging file on one drive at a time. Re-boot, and defrag that drive.
2. Compact the registry. Generally, Windows slows down as the registry gets bloated.
Make sure that keys for hardware and software that is no longer on the system have been cleared.
There is an article on compacting the registry for 9X at
I don't know how much applies to W2K.
I use either Norton WinDoctor, or Ontrack Fix-It to clean and compact the registry.

Microsoft recommends a pagefile that is size of memory + 12Mb. Yours is bigger than this and depending on what you're running on the box, should be adequate.

I do wonder about splitting it across three partitions, though? Are they on physically separate disks? Or three partitions on the one disk?

If the latter, then you'll actually slow the machine down by fragmenting the pagefile over three areas of the same disk!

I would run performance monitor on your machine for 15mins or soand collect information on what its actually doing.

You can start the performance monitor by typing perfmon in a command window. Choose some counters from the the following areas...


After looking at the results, you may find you need to actually enable the disk monitoring by typing diskperf -y at the command prompt and restarting.

You're looking for a process that hogs one or more of the machine's resources. Hopefully you'll easily spot it...

In addition to TimtheTool Guy.

System performance is INCREASED when you distribute temp files and page files on drives that do not contain the operating system.

System performance is DECREASED when you distribute temp files and page files on partitions on the same drive (which also holds your OS). Since you're on a laptop (one hard drive), create a partition of 770 megs, create a 768 pagefile on that partition (this ensures that the pagefile won't become fragmented, which is the only performance area you can fully control). Windows will warn you about not having a pagefile on the OS partition, if you've never read thru a crash dump heap, you're not missing anything. You'll just increase the Blue Screen time if the system has to debugsomething and there's no pagefile on the OS partition.

Good Luck
