MaxDB performance on hardware and VMWare instance
Have just made a homogeneous system copy of our Solution Manager 7 production server (hardware instance) onto a VMWare instance to use as a sandbox. Noticed that the performance of the copy "feels" significantly worse than that of the hardware installation.
Is there any commentary/insight out there regarding special tuning or circumstances or actual performance penalty for MaxDB/SAP on VMWare instances? In other words, should I expect copies (or even fresh installs) to be slow on VMWare?
Here are the config details -
SolMan (hardware instance) - Dell PE2850 2 x 2core 2.8 GHz Xeon, 6GB memory, PERC 5i RAID, O/S+ log files on RAID1, rest on RAID 5 filesystems. SLES 10-64 SP2, MaxDB 7.6.04.11, SolMan 7 SP13. Solman Copy: VMWare ESXi 3.5 Update2 on Dell PE2950 2 x 4core 3 GHz Xeon, 32GB memory, PERC 6i RAID controller, all RAID6. VM instance allocated 4 CPU, 8GB memory: SLES 10-64 SP2, MaxDB 7.6.04.11, SolMan 7 SP13.
Thanks for your insights!
