Hello
I have a Intel Core2 Quad CPU and I configured some 2 VEs
HN with Centos 5.5 64bits e VEs whith Ubuntu 9.10 64bits
In each I run the same script that creates some temporary files on disk.
When I run this script on only one VE, the performance is good when the cpulimit is 400. The runtime is 10 seconds
If I set the cplimit = 200 the runtime is 35 seconds !
If I run in 2 VEs, with cpuunit = 250000 and cpulimit 200 the performance is very bad.
I check, using the top, that processing in each VE reaches 100%
My CPU check is
Current CPU utilization: 447332
Power of the node: 531946
The cpuunit in the HN is 26600
Are there any parameter I can change?
Some tip ?
Thanks
Renato
