load average

[Tim X]

Hi,

I have simple question, I use virtual host and I think that this server is slow and overloaded :-(
Can anybody experienced tell me which numbers in load average are good and which are bad ?

Thanks

just tell your load averages and the server specs, then we can tell. :rolleyes:

[Tim X]

they write that configuration is:
Quad PIII 700 MHz Xeon CPUs, RAID 5, 2GB RAM
and now i see there:
load average: 19.42, 30.69, 28.43
Mem: 2061252K av, 2050544K used, 10708K free, 0K shrd, 57688K buff

etc ...

load averages around 20 are indeed too much, 4 up to 8 should be normal, on virtual hosting they may sometimes reach 30 or 40, but only and only for a couple of minutes.

[Sureal]

Yeah those load averages are really high...

These are my load averages
Last 1 minute: 0.10
Last 5 minutes: 0.03
Last 15 minutes: 0.01

[Tim X]

I think too that this is too much, and sometimes are there numbers over 50 :eek:
And results is that than my sites there works bad and I only loosing traffic :confused:
I have now new dedicated server, there I will be alone and I hope that my traffic must only grow there :D

And which server you use ? (I mean configuration offcourse)
And how much traffic you have there ?

[Sureal]

I am running...
Redhat 7.3
Plesk 5.0 Standard install
Apache 2.0
1GB DDRAM
100GB EIDE 7200RPM
Intel Pentium IV 2.0GHz w/512K Cache

I am putting thru about a 100K-150K/daily

[Tim X]

This sounds good.
I will have now same processor but only 512 MB ram and 40GB hdd.
But I think that this will be good for me now too :)
I am getting about 50k/daily now, but I hope that this will grow faster now ;)

what hosting company?

united colo, I had to get them to custom install Plesk, apache and redhat, There servers only run Ensim, which i hate, And they run Redhat 8.0 which won't work with plesk 5.0 so i had them install redhat 7.3 etc... But my server hums along...

that's a quad CPU server.. you shouldn't be worried about a server load of 20.
My machine is always running on 20 and it can handle loads up to 100. At 150-200 pages start to load slow. If the max load on that machine is 50 then all's OK. Even 80 shouldn't be a problem.

Yeah it really depends on the machine. But what your pages starts to load slow, you know there is something wrong :)

But in ssh, if I run TOP, I see there only information about 2 cpu, maybe it is only 2 cpu machine.
I think that loads there is too big because my sites which had stable traffic few weeks now without any changes started loosing traffic :(
But yesterday I made DNS changes and now I have about 1k/hour on my new dedicated and averabes are there less than 0.01 :)
:finger: old hosting company, own server is BEST :D

[Sureal]

Yes it is way better to get your own server, and they are so cheap now, everyone should have one :)

Oh my god!

all over 5 is OVERLOADED!

Statistics says that server is NOT overloaded if you have 0.xx (e.g. 0.80). All above is too many. Let's say that adult sites are quite challenging for the server, so it's OK up to 5.

But if you have something above 10 or so, change your host IMMEDIATELY! They are losers and your business will ruin soon.
Yes, that's the reason you are slow. Second one can be Cogent lines.

Check our adult hosting, we'll giving free content and our load is max. 1-2 on every machine. :-)

have a read up on what those numbers actually mean, and you'll have a better understanding of the servers performance.

One of the best indicators of a stressed CPU is the load average. This value indicates the average number of processes that are ready to run, but are waiting for access to a busy CPU. A CPU that's 100% busy but has no processes waiting represents an entirely different situation than a CPU that is 100% busy and has a load average of 10.

Nice, now I know that previous server (from any unnamed company which promote here in board their hosting too :-) ) where I host my sites on virtual account, was pretty fucked and current is pretty good for me :)
And price is hot :bounce:

[stramm]

a own machine is the best solution :))

and not every machine over an average of 5 is overloaded. Eg. you have masses of galleries and all get accesses, then a lot of processes are running (if you use apache). Means your load soon will be high but you still have idle CPU time... so no problem at all.

On my machine are 2 brownies, 6 UCJ, one RB4, ~1k galleries, 10 free sites and 2 pay sites. It's burning ~40 mbps. You bet that there are a lot of simultanous processes and that pushes the load to 50 or sometimes more. But as long as there's idle CPU time I don't worry (and as long as the sites load fast).
