server load techie question (top) - GoFuckYourself.com

CPU states: 7.0% user, 0.0% nice, 91.9% system, 1.1% interrupt, 0.0% idle

In Top, does %idle mean the same thing as in Windows? Does this mean the CPU is maxed?

SoundMan · 03-19-2004, 07:52 PM

91.9% system is not good.

I hope to god you are running a few scripts (as in building a site with tgp script or something like that) while you checked that....if not thats really not good lol.

Los · 03-19-2004, 09:20 PM

do a ps -aux to see what is running or top and see whats killing your cpu

fuzebox · 03-19-2004, 09:31 PM

Weird to see system load that high, and not user... Are you swapping maybe?

Sami · 03-19-2004, 11:01 PM

Yes that means your CPU is maxed out.

If you have a site trading script thats using mysql and its not optimized, they usually cause that.

But like it was mentioned before,
do a ps -axf

to see whats going on.

fusionx · 03-19-2004, 11:25 PM

Unfortunately, I'm on a virtual server - shared host.

::Rant mode on::

I called this morning (9 am EST) and reported a slow site - cgi-bin stuff was crawling. Top showed 0.0% idle. There are several TAR processes running sucking up all the CPU. They said they were running backups.

I checked again at about 9:00 PM, and sure enough, still slow. The same TAR processes are still running. I called back and expressed my disbelief that a tar backup would cause this. They then said they were moving some sites off the server and this might be why.. might.. the tech did say he'd check into it, and seemed concerned.

It's 1:22 AM and the same TAR processes are still running, and the site response absolutely sucks.

I'm no unix admin, but at least I know about Nice. Sheesh.. talk about a wasted day. Wanted to set up two more sites and can't even modify a template in Autogallery SQL.

Anyway....

::rant mode off::

Thanks for the responses!

Post the processes listed when you run top and your memory stats from top.

How often does your host run those backups? Is that daily?

salsbury · 03-19-2004, 11:41 PM

nice wouldn't help in this case. nice doesn't help with disk intensive processes - only with cpu-bound processes. what *would* help however, is for them to only run one tar at a time instead of 7. 7 makes the disk have to work awfully hard seeking all over the place.

i'm betting that you're on an IDE-based server. that'd explain the extremely high system CPU.

it might be time to find a host that uses SCSI exclusively. even on a shared server, you should see far fewer slowdowns from stuff like that.

Nah - I think it's a one time process. I've never had a day where response was slow all day long.. a moment here and there - no problem.

CPU states: 0.9% user, 0.0% nice, 3.1% system, 0.4% interrupt, 95.6% idle

Ahhh... perfection

Webair Mike just got it hooked up. That's why I love Webair. Sometimes they have issues, like every hosting company, but they always get it fixed. Must be a new tech :-)
