Are you sure it would show up as "User" load and not as "Wait" ?<br>
On linux "TOP" it shows something like:<br>
%Cpu0 : 99,0 <b>us</b>, 1,0 sy, 0,0 ni, 0,0 id, 0,0 <b>wa</b>,
0,0 hi, 0,0 si, 0,0 st<br>

Are you using RAID on the disk storage? IME, RAID can more than halve
the speed of the proxy. Although the CPU thrashing effect is mostly
hidden away out of sight in the disk controller processor(s).</pre>

6-core of Intel(R) Xeon(R) CPU E5-2667 v2 @ 3.30GHz<br>
It's a vmware VM with a NetApp 266TB storage. This VM has access to
2 different LUNs in 2 different controllers to a bunch SAS HDs, <br>
