YUM update? - Page 2

**Bigjohn** · August 8th, 2006, 6:53 PM

yah, I heard that one... but
you should be getting what you pay for.

Perhaps they need to re-initialize your server/image.

Well I've had a ticket in the Support Division, Abuse and Security 2 times, 3rd Level Support 3 times since I've had this VPS from May and if they can't see there is a problem by now I have no faith they can find it. Shoot all that in 3 months. Not very happy. Do not have the need for a Dedi and not going to go backwards to shared. so if this don't work out soon I'll just dump it for I don't even want to bother with another Host. I'll just walk away from it. Maybe just not meant to be! oh well.Shoot the forums so the 3ed one may get canned in a couple weeks anyway.

Your CPU% in the chart is your usage of your CPU allotment. The CPU load in the graph is a top command for the entire server. If you have 10 VPS users on your server and each of you are using 10.5% of the CPU for an entire server YUM update, that would be 105% of the total server for YUM alone.

A load average is divided by the number of processors, so a load average of 5 is equal to 1.25 on 4 CPU systems, or a delay of 25%. Not bad stats for updating 10 servers in one box at the same time.

At this point if someone should have called one of your pages, instead of loading in 2.5 seconds you could expect a load in 3.125 seconds.

If .625 seconds (or less) delay is a valid means to be whining in your beer, yes do keep sending support tickets, take productive time from support, and make ones with priority issues wait longer for their valid tickets.

Complaining and threats are not generally expected as a Christian attitude, especially from the preacher. If you go camping and fishing, walk -- the price of gas is a valid complaint.

cowboy that is just to funny, and I hear it allot. it is like folks think Christians are non-human or something. LaughLaughLaugh

man I am just as human as anyone else and a disabled veteran at that. my bishop and shrinks tell me they would be worried if I didn't yell scream and complain about things. and my doctor says that just shows I'm still alive.

I'm not perfect and far from it and not even going to try to be perfect.

Thats a great summary Cowboy - gonna copy that down for future reference. Think I will try and compile some of this data and others and create a simple guide to understanding your VPS. There is a lot of confusion on how VPS works (including me) so this is good stuff.

I'm not sure, but when trying different versions of Linux, I tried one with YUM on it (Fedora I think), and YUM takes up alot of resources.
When it runs it depends on how you have it set up I think.
I googled it, and most sites said that YUM will use all avaiable memory to try to get what's doing done as fast as it can...

Old saying--if ya got it--flaunt it (or in this case--memory--use it) cuz it ain't doing much good just sitting there unused.

There's suppose to be a C version of the YUM metaparser being worked on and that's suppose to reduce the load.
I read that Python 2.5 might help speed up YUM...

Well I don't know for sure if it is the culprit hogging my resources I just managed to catch it 2 nights in a row. Just found that odd.

Just trying to figure out what is behind pushing my server load up to 5, 6 and I've even seen it up to 8 and 9 a couple times. That is a bit high for our VPS CPU setup.

**Bigjohn** · August 9th, 2006, 1:01 PM

See if you can get support to change the schedule of YUM updates on all the Virtual servers on that one "box". If there are 10 virtuals, then they could do the YUM updates every other hour starting after the backups are finished....

That might spread the load.

What I'm thinking is that each of the virtual machines is a 'clone', so they all have the same exact update schedule by default.... and as Cowboy correctly illustrated, each device grabbing disk and CPU at the same time, whoops... server pegs up!

**Skipdawg** · August 9th, 2006, 2:34 PM

Good idea. If I see it again and affecting the forums will drop a ticket and see if they can do that.

I went in last night and removed some things via WHM I knew I did not need. So we shall see if that helps any.
