[otrs] Mysql | Support sql benchmark wrong?

Hi there! I have migrated our otrs installation to an ubuntu 12.04 lts server (formerly 8.04). The Support overview states "everything is fine" - is made a view commandline benchmark tests of the mysql 5.5 server ... all stated a very good performance, the Otrs itself "feels" very fast BUT the included support tests claim an Insert,update,delete time of 32s (Select 4s) when starting the Normal test. Could it be that the tests are simply wrong? regards Martin
