VMware 2.0 hosted servers running super slow

I have a windows 2003 SP2 server with a quad core 2.33ghz and 16Gb ram

I am hosting four VMware windows 2003 SP2 servers each with 2Gb ram

Two of these are running just fine, the other two are verry slow to boot and are "jumpy" when up

For example if i copy files from the network down to the VM it will run fine for a minute, the freeze, then run fine, then freeze, etc..

All four VMs are made from the same 2003-stock VM server Image
I have the VMware tools installed on all of them

VMware Infrastructure Web AccessVersion 2.0.0Build 116487
VMware ServerVersion 2.0.0Build 116503

Any trouble shooting recomendations?

I would take a look at I/O on your host.  VMWare server really isn't all that great for hosting big machines like that.  I'd strongly recommend looking at ESXi, which is also free.  I've found performance to be a LOT better.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Good Morninig

The OS are all 32 bit, including the host server
The three drives are 300Gb SATA in a R5 for 600Gb
100Gb OS partition
500Gb VM partition

I/O is OK on server, per perfmon

We are looking at replacing the host OS, but the need for speed is imidiate

dual nics, traffic is minimal

When I run Perfmon, I see the disk I/O is at 100% for 80% of the time.
I may need to split the drives so that each VM has a spindle

Windows 2003 running VM2.X has issues.
If the host has 6Gb of Ram, and you grant 1gb to the VM you are fine, if you grant 2Gb to the VM the paging is out of controll

We migrated to ESXi, and resolved our issues.
