CPU usage is 100% on a Debian server even when 5 competing users are doing 1 operation per second, the CPU picture looks something like this: Cpu(s): 82.1%us, 17.9%sy, testing siege -c5 -d1 -r10, me it seems that this is too much load for the Intel® Core (TM) i7 processor declared by the hoster CPU X 980 @ 3.33GHz 1600 Mhz , while there is a lot of RAM left, the server has a bunch of Nginx + Apache + php-fcgi + eAccelerator + memcahe, it is being tested on an empty site managed by livestreet, I look at the CPU load data through top.
How to check how much CPU resources the hosting actually gives out? Or is this load considered normal?

Just on the cheapest VPS from clodo.ru I polled a page for 10kb + 100kb of pictures + nodejs made a request to MongoDB and returned JSON.
Completed 1000 requests at home
ab -n 1000 -c 5 http://*****.net/
Load increased from 1% to 6%

Run some processor benchmark, compare the result with the one found on the Internet (preferably for a processor of the same series, megahertz are different) - find out how much your virtual machine can use a processor.
Compare the results of a test run at different times of the day - you may find out if the hoster is playing with oversell.

I'll add my 5 kopecks ... check, what if your case?

FirstVDS (this is Virtuozzo, a commercial version of OpenVZ), all of a sudden, for no apparent reason, all downloads in php using curl_ ... incredibly slowed down and gave out a load of 100%, after a few hours everything was gone, the reason was not identified.
ps using curl_multi_… eats up memory - it flows very strongly, the bug has been hanging on the tracker for a long time, and periodically it closes and opens

And what do they virtualize? If it's openvz/virtuozo, it's better to change the hoster right away. This is an oversell in 99% of cases, except for the general fs, problems with memory allocation and other unpleasant surprises.
Also, look at what specifically creates a load for you. For example, maybe just some very bad query mysql is trying to digest. =)
