Hello,
I have just installed my new PIV 3.0Ghz.
The new technology of the PIV 3Ghz makes it possible to see this PIV like 2 procs (like Xeon)...
With Firebird 1.03, considering which it has a parameter which makes it possible to tell it on which proc it must work, I make some tests.....
Result of the tests:
On a request which take 2,8S on the PIV 3Ghz :
On a PIV 2.5 Ghz
1 user = 3,079s
3 users = 5,578s 5,172s 5,953s
On a PIV 3.0Gh without modifying the IB config
1 user = 2,813s
3 users = 3,313s 3,609s 5,062s
On a PIV 3.0Gh with CPU_AFFINITY 3
1 user = 2,859s
3 users = 3,187s 5,359s 5,703s
I launched the Taskmanager which shows me well that in the first case alone 1 proc works, and in the 2nd case, both works....
Is what somebody has an idea of why it's not faster when using 2 procs ?
Thank you very much
