Slow performance on DL380 G3

[IdoF]

I have installed ESXi on HP DL380 G3 and installed one Win2K8 server on it and I am getting very very slow performance the installation took me more than 2 hours.

The OS is on a Mirror and the VM is on another volume on RAID5.

How can I get My ESXi to give better performance?

Thasnk in advance,

Welcome to the forums.

Can you please provide more detail about the hardware in the DL380 and also about how you set up the virtual machine?

I believe a 380 G3 has hyper threading? if so disable it within ESXi and reboot ESXi and then boot up your VM.

that is what the problem was with my similar box.

When you configured the bios / disks, did you do fast initialization? Could have had the raid being built while you wrote to the disk system. Also look into the battery-backed write cache. Lot of times when you order DLs they don't ship with the BBWC which can affect disk performance, I don't see that causing a 2 hour install though.

Check your disks to be sure you don't have a degraded array. You could also do a memtest on the system, though with the install the bulk of the work is disk i/o. I've also seen bad CD drives cause poor install performance, you could try using an external CD or if you have the ILO available, do an ILO remote CD install.

Its the Hyperthreding that did it.

Thanks very much

Yes indeed.

Switching off hyperthreading could raise performances, but why don't use hyperthreading if available.

This seems not to be logical, isn't it ? Anyway, ofcourse it depends on your machine / server you're using ...
