VMWare ESXI 5.0 S L O W

I have a recent install where I have ESXI 5.0 running on a DELL Power Edge T420

I have the following VMs running

Three windows 2008 R2 x64 Servers
  1- Domain Controller
  2- Application Server
  3-  SQL 2008 R2

4 Windows 7 Ultimate x64
1 Windows 7 Ultimate x32

The windows 7 machine all run VERY SLOW.

I have installed the VMWare tools.

Video Driver is set as the VMWare 3D driver

If I open a windows explorer window and click on it and drag it around the screen it lags like crazy.

Where to begin??

how much memory have you allocated to Windows 7, 2GB and 2vCPU?

what datastore are you running on, not a single SATA disk?
vmware is mostly the i/o problem of the speed not the cpu or the mem. so you have to check the parameter if it is fast enough. mostly sql server kills i/o they eat this for lunch. Best practise for sql is to have a lot of hdd instead of some and big ones.

I have 4 Gig of Ram assigned.  2 Sockets with 2 cores each.

I have 3 500 GIG 7200 RPM SATA drives set as a RAID 5.

I have 2 Six Core processors and 64 GIG of RAM.

I can get the exact specs if you need.

I actually do not even have SQL running yet.

It is just the DC and the APP server and the 5 workstations.

The bottleneck is the datastore, and the 3 RAID 5 SATA disks, performance is very slow using SATA disks.

see my EE articles

HOW TO:  Performance Monitor vSphere 4.x or 5.0

Unfortunately, the performance of your server is let down by your poor disks.

4GB RAM for Windows 7, and 4vCPU?

reduce the RAM and processors to 2GB and 2vCPU.

The more vCPU you have running SMP, can slow the virtual machines down.
