VPS — why such load and is it normal?

There is a simple VDS on CentOS 6.7 + VestaCP.
*linux does not understand at all, ordered a VDS, there was already a penny and Vesta.
Threw 3 site VP, 1 of them is the MultiSite of 29 domains.
All in the cache. Update the content managers of the sites rare.
But the memory of a nearly Packed

if reboot to make everything OK, 100 MB and it suits me. But she's growing up "in the ceiling", and I plan to increase the number of sites at least 2 times. What to do?!)

caching to speed - I Windows understand.
Introduced free-m, according to the description in your link is the bad one?

Solution
this is linux man. It's in the OS buffer most likely. free-m show that will give. www.linuxatemyram.com
updated the question, issuing the command free-m, in cache, not so much - jamie_Breitenbe commented on July 9th 19 at 13:38
you have almost all the buffer she is! everything is fine with you all in the buffer. she is to be released at need. If you're Kalita he can throw echo 3 > /proc/sys/vm/drop_caches or on the crowns to frame every hour. But doing so is completely unnecessary - douglas_Wehner commented on July 9th 19 at 13:41
: : no, I understand that if indeed there is a disposal for the sake of acceleration, then touch it makes no sense to use :) - jamie_Breitenbe commented on July 9th 19 at 13:44
: just panicked that on the 3rd day already exhausted all the resources of the server. Never thought that here, as in win - scored all of the memory "most popular data", roughly speaking :) - jamie_Breitenbe commented on July 9th 19 at 13:47
you have more than 800 metres in the buffer (it is free memory) if need OS it will spit itself. Everything is fine with you not pesukei=) - douglas_Wehner commented on July 9th 19 at 13:50
carefully reviewed the screen, and he understood :) - jamie_Breitenbe commented on July 9th 19 at 13:53
