Fedora's desktop is running very slow


Hello.

I have a box with Fedora 7 fresh-installed and runs very slow. Nearest I can tell it's the desktop that's slow as cold mollasses.

Following boot, I bring up the system monitor (about 30 seconds from click to a visible application) and find the CPU occasionally spikes at 60%, otherwise runs less than 20%. Process list shows the monitor using 20% CPU while the rest of the processes are sleeping.

RAM size is 256mb with 60% used. Swap space has 512mb available with 0% used. So I don't believe RAM or swap space are issues.

I've seen similar issues on the web but not with these symptoms, that I could see.

Could anyone help me? Please?

Tom D.

Try disabling the unnecessary services, it'll help a bit.

I added 250 mb of swap space for a total of 500 mb (using mkswap and swapon -a) .... is that what you're talking about?

Adding this swap didn't help things. But can't hurt to leave it there either.

Thanks!

the swapiness value is how much it moves stuff to swap. for example a swapiness value of 100 means it swaps out alot, and 0 means it doesn't swap at all

Hmmm.... Where would I locate this swappiness value?

This was my first shot at setting up the swap file.

Hi, y'all!

Well, I did stumble into what I suspect is the cause of my Fedora 7 box' response being slow. Another Fedora 5 box slowed down too.

I suspect either three subnets being set up on the same set of cables (would that really cause problems?) or my DHCP server (in a separate box) is spitting out the wrong set of addresses. When two of the three subnets are shut down, the F7 and F5 boxes' response seems to be OK.

I know you guys suggested shutting some services down -- and I did -- at least everthing but the network service. AUGH!

Thanks anyhow! Problem solved...at least as far as the slow response is concerned. I just need to see what's up with my DHCP.

Tom D.
