Hi
Today I have in my server, 18 VEs. One run the system in RoR e the others 17, running basically the same application that runs 19:00 pm until 8:00 the next day, a period that the system in RoR is rarely used.
In those 17 VEs, in some moments the application runs a routine that handles small images .. When these 17 VEs are processing with low or zero (outside the above period), this routine is performed in a maximum of 3 seconds in a VE.
But when I run more than one VEs running this same routine at the same time is very slow, taking more than 30 seconds each execution
Below is the configuration of my server, I'm using the VEs and command vzcpucheck.
Does anyone have any tips on how to improve this?
Thank you very much
Renato
