There are many things that you can do.

*  Ensure disk type is non-dynamic
** The tool to change this is vmware-diskmanager or something like that

* Ensure vmware-tools are installed in the guest

* Ensure you are running on Linux host, because Windows VMware hosts are slow!

* Do you have a CPU with virtualization extensions?

* Do you have more than enough RAM in host and allocated to Guest?

* What does bonnie++ report while the guest is running?

* Did you disable debugging options for your VMware guest?

* Did you disable logging?

* Did you enable the mem_trim option in the VMX file?

* Did you upgrade your virtual hardware?

* Are you running the latest VMware Server 1.x?  2.x sucks btw...

I have much experience with VMware from my time at Cisco developing
the Cisco Computational Cloud automated tested infrastructure (4096
simultaneous virtual machines on 64 physical machines)

There are many other non-standard VMX options you might utilize.
Google for them...
