Gents,
i'm running OVZ on an xeon dual quad core system, that means 8 cores and a lot of memory (16G).
I try to find out the max usefull number of running VE.
Doing all the same small job.
Running VEs i got
(all values are seconds taken from time)
1VE
30real 11user 25system
2VE
37real 11user 36system
3VE
60real 11user 70system
4VE
97real 12user 124system
8VE
276real 14user 260system
I wonder why the amount of system time increases so dramatically.
Can't believe that 2VEs are the maximum number to get the highest troughput for this applikation.
Especially when i compare 1VE with a (nearly) 1:2 ratio of user:system with 2VEs or 8VEs where this ratio screws down to 1:19.
Any idea?
best regards and thank you for OVZ!
This is the conf i used:
