OpenSUSE Hardware :: Slow Performance With Mutexes And MySql On Multi Core CPU - AMD Phenom II X4 965 - With 11.3

I have installed OpenSuse 11.3 32 Bit in a virtual machine on an older computer on a Windows XP host and on a new computer with AMD Phenom II X4 965 processor.

With sysbench I tested the performance of mutex and on the new computer it is 3 - 4 times slower than on the virtual machine. Other performance tests with sysbench for CPU, memory and threads are faster on new computer like expected. I tested this, because I have a slower performance of table creation in MySql tested with sql-bench, where creation of 10000 tables lasts 45 seconds on the virtual machine but over 400 seconds on the new computer.

I have tested with kernel-desktop and kernel-default but there are not large differences. File creation was tested with bonnie++ and is on newer computer faster as expected.

My questions are:
- Why is the mutex handling on the multi core CPU slower than in the virtual machine and how to speed up this?
- Or is there another reason why table creation of MySql is so much slower on multi core CPU?
