Thank You! Thank You! Thank You! <br /><br />This post saved my vmware. I was thinking of switching over to VirtualBox as I had good performance experience with it over a year ago but due to lack of features/maturity i stuck with vmware.

Yes its a bit out of date and also from these tuning options vmware defaulted some in the latest 2.x server.<br /><br />I was doing performance tuning on a my vmware server with a Quad core proc and 8 gb ram.<br /><br />My apps were so IO sensitive that I decided to switch the storage backend to SSD hoping that might helps but there was some unexpected problem with probably the motherboard.

A-ha- but will you use OpenSolaris or Debian/Ubuntu or other &#39;nix to host the VM? To ZFS or not to ZFS... that is the question (yikes!) I&#39;m playing with ESX4i atm, now RAID etc is no problem, just the USB on the dumb HP ML370G4 host is crap.

Thanks for the comment!<br /><br />I&#39;ve actually switched to Virtualbox now, I wrote that article in mid 2008 so it&#39;s a little out of date.<br /><br />I&#39;m working on a new article to update converting Windows from physical to VM and run your VirtualBox as a personal server.<br /><br />I think it actually outperforms VMWare Server, and it has lots of really great features that Server

Sorry, my comment before didn&#39;t say- I run MySQL and IIS on a win2k3sp2 guest. I went from running win2k3/1 uniprocessor to win2k3/2 smp and guest stopped stalling. I run 200GB in the guest fs running 1TB SATA disks in RAID. (beware: Fools tread here it is foolhardy using 300GB+ disks, let alone SATA ones).<br /><br />Why 1.06 not a later ver? 1.0.9 isout now.. 1.07 I heard was trouble. Is

Was about to ask which version of server were you discussing and there it is in a later comment... 1.06 (perhaps sensible) given what I have been through, so I was reading with keen interest - and thank you for taking the effort to detail your experience. I always ran OpenSuse to try and piggy-back off the SLES 10 support that vmware offer. Had terrible trouble with disk IO though always

I have to say dude. When it comes to Virtual Iron, XEN, VMWare, etc. I consider myself a pro. I learned something today. This post saved me alot of time and effort. Keep it up.

Did not research the proposed changes before doing them (I know: brainless) but the result speaks for itself - I went from 12 hours for backup and verify a Win SBS 2003 R2 to 1 hour and 12 minutes.<br /><br />Thanks a lot for this great post.

I'm running Ubuntu 9.0.4 and VMWare Server 2.0.1. When I try to implement the recommendations here, my VMNet0 bridged adapter stops working for my XP guest VM. Any suggestions?

I prefer to not split them. The reason for this is that splitting them increases fragmentation at rest, and potentially forces a lot of seeking which increases contention.<br /><br />I haven't tested that theory though.

You mentioned that performance improves when you pre-allocate the disk space. Have you noticed any difference in performance if you split the disks into 2GB files vs. storing them as a single file?

Your settings really made a difference, thanks!<BR/><BR/>However, the most performance was gained by assigning the virtual machines one processor instead of two. I learned that it's a very bad idea trying to give a W2K3 server (32bit) guest two cpus, if the host is a 64 bit ubuntu 8.10 server (if you're using vmware server 2).<BR/><BR/>Unfortunately, removing one cpu in the virtual machine was

Um. Fantastic. Thank you. <BR/><BR/>I also added two more kernel parameters.<BR/><BR/>On the host:<BR/><BR/>elevator = deadline<BR/><BR/>on each linux guest:<BR/><BR/>elevator = noop<BR/><BR/>This works, but I have not done the sort of extensive testing that you have.

useNamedFile = false when backed by /dev/shm forces the swap to be stored in physical memory, and only dumped to the host swap file when necessary. When paired with vm.swappiness = 0 it won't use any of the server's swap unless it's out of memory.<BR/><BR/>Of course it offloads disk based memory management to physical memory, that's exactly what you want to do! You never want to read or write

Some of your recommendations could put people in worse shape, IMHO. For example, useNamedFile = FALSE places more memory management burden on the physical RAM of the host. The option was really meant to relieve slowdowns if someone was running a VM off a USB drive. If you engage that option and don't have enough physical RAM to cover the difference, performance will be worse than if it had been

Seriously, thank you, thank you, thank you.<BR/><BR/>I was almost ready to abandon VM Server on Linux and buy a stupid Windows Server after all the searching I did online.<BR/><BR/>I finally found your post and applied the changes you mention. Although my server was Fedora, the concepts were the same and for the most part even the syntax.<BR/><BR/>This solved my problems 100%. Thank you again.
