Hi,
I have one server with one quadcore processor.
It is necessary to configure MAXCPU = 3 ?
Or Its better to use MAXCPU = 1?
Is there any other configuration when I change my environment to a quadcore processor?
Best regards,

Just SAPDB is running in this server, nothing else.
Data Collision.
When I had a dual core server, sometimes in the dbanalyzer messages, I could see some data collision rate.
This is normal when two UKTs tries to access the same data at the same time, the kernel will take care of this.
If you use less processors the requests will queue up instead of being processed in parallel.

Thank you for your answers.
I set MAXCPU to 4 and everything is fine.
It solved my performance problems.
Thank you !
Hello Daniel
In addition to Markus' answers:
In your situation:
- set MAXCPU=4
- no

Nothing else is running.
Just SAPDB.
So, If I change MSXCPU, what abou collisions?
BEst Regards,
No one else is running what?
What do you mean with collisions? Colliding what?
It depends on what else is running on the system and how the load distributes between the application and the database.
We always set MAXCPU equal to the numbers of cores in the system because the chance, that all 8 CPUs will be used 100 % by the database is very low.
