I get very poor read performance with ESX 3.5 fully patched on 3 servers.
I've done HD Tune test on all the VM inside these servers and they all reach 13MB/Sec read transfer rate.
I've done the same test on the same machine without ESX, a physical Windows 2003 R2 and I get an average of 65MB/Sec .
Please tell me what I am doing wrong.
These are the specs of my servers:
Dual XEON 3.06ghz
6GB of RAM
6x 144gb U320 10k RPM in RAID5
I've tried enabling/disabling hyperthreading without noticing any difference.
