CPU/Memory Usage Question
CPU/Memory Usage Question
(OP)
Hello,
I am in the process of updated a view in one of my drawing files and it is taking along time. I open task manager and it says my CPU Usage is at 100% and my memory usage is 486,392K/4,035,016K. I am not sure what I am looking at, but is it possible that I have something set wrong, like my swap file? Why wouldn't the computer be using more of its memory? I just switched from another Zeon with exact hardware, but this one seems alot slower (same network line).
My computer is a Dell 1.7G Xeon Processor, 2G RAM and I am running SWX SP3.1.

RE: CPU/Memory Usage Question
Windows can be extremely dumb when it comes to using the swap file. You could try reducing the size of the swap file. Normally your ram and swap file should add up to 1 - 1.5GB. Since you're already beating that quite handily with your ram alone, it wouldn't hurt to drop your swap file size. If I'm reading your numbers right, you've currently got a 2GB swap file. Try setting it to 512MB.

"Mem Usage: 486,392K/4,035,016K" means Limit is 4G and 486M is used. You stated you have 2G RAM (How I envy you!) and as of the result, Swap is 2G. Basically, up to 2G (RAM), swapping should not happen and Usage is only 486M. Therefore, the bottleneck is not going to be the memory, especially when CPU usage is 100%. However, I am not sure how you confirmed you have 2G RAM, but look at "Physical Memory (K)" of Task Manager. If Total under Physical Memory (K)" says about 2G, it's OK. Otherwise, RAM is not recognized. By the way, I have never seen a drawing (SLDDRW) which is 486M big.
Next is CPU usage. You stated you have 1.7G Xeon and I am sure it should be fast enough. CPU Usage shouldn't be 100%, unless you have a low level video card, that I hardly doubt through. Execute SW and go to Tools>Options>Performance. Uncheck "Use Software OpenGL" and see if the speed is improved. As long as you have a qualified OpenGL video card, it should handle graphic without using CPU.
If the speed is improved by un-checking the option, you have a video card issue including drivers. If it isn't, check with other drawing. If only the drawing is slow, go to File>Find References and make to see how many files are loaded through network. Copy all to your local and try to open. If it's OK, then you have a network issue.
Hope my troubleshooting helps. Good luck.

Go to the following Web Site and select nVidia to see the result.

As I mentioned at last, most likely bunch of files are loaded over the network. Copy them temporally as I described to see the speed improves. You can just see how many files are leaded over the net by going "Find References" without phicically copying.
CPU Usage becomes 100% time to time, but if it should not stay 100% for a while. In that case, the PC is not optimizes to handle the file, like needing faster CPU, bus, HD or etc.

What components determine the speed of a network connection?
RE: CPU/Memory Usage Question
You dodn't indicate how many files are loaded over the net, but I can see two cases, Intranet and Internet. I don't know how your network (file server) is connected, but the net speed varies by many thing and typically you can't do much about.
I believe you want to make sure if it's network issue at least. Otherwise, your PC is just fine. (hardware and configuration)

I have had 2 different Intel clone boxes have too much RAM, one Dec Alpha with a bad chip, and a 933 Dell box with too much RAM.
RE: CPU/Memory Usage Question
Thanks again fore the ideas.
RE: CPU/Memory Usage Question
It does sound like your problem is elsewhere though. If it is loading over the network, you should find a way to change that and bring them locally to your disk to work on. PDM systms usually handle this automatically while managing the potential conflicts of concurrent use.
Remember also that total network traffic can drag down even a fast network. Also other interference or bad connections, hubs, etc. We have seen these things happen.
