Problems include:

*) User error when configuring
*) Resources available which can be unknown on a hosted vm platform.
*) Countless other variables about the setup not known at this time.

Everything discussed thus far is conjecture and supposition so there is not
really any concrete subject to comment on.
This is why we do not usually engage on performance and VM related subjects.

We offer commercial assistance for matters such as this where it requires
possible investigation and time spent to discover the source of an issue.
