Your normal workload.
I am doing some IO throughput, swap throughput and database tests,
however those are probably not representative of what YOU throw at
the VM.
There are no VM benchmarks that cover everything, so what is needed
most at this point is real world exposure. I cannot promise that
the code is perfect; all I can promise is that I will try to fix
any performance issue that people find.
