Upgrade is done.
VCS gives load on Intel Core i7-2600K @ 3.40GHz as shown on pic below:
The CPU is loaded only on ~40%, the second core works almost on 100%. Looks weird
I wonder why VCS doesn't use all cores on maximum?
And maybe there is any way to start second copy of VCS on the same server? Maybe in this case it will be possible to load CPU on 100% ...
Video encoding process includes not only math operations, but data moving also. Also OS uses some CPU time.
Therefor CPU isn't loaded on 100% while encoding.
