Morning
This may be slightly off topic as it has nothing to do with Linux, but
since vmware seem to be popular, we may have something to share. I do
not like vmware and my beef with it is lack of visibility.
My current problem is making sure that we are not I/O bound. On xen
or kvm, this would be a walk in the park. On vmware, well don't know
how to be certain of that. I have checked esxtop but it seem only to
show read write throughput, not whether the system is I/O saturated.
I usually get that information from utilization when using iostat.
So the question is, how do you guys monitor vmfs performance? Have
there benchmarks between vmfs against any of the Linux based file
systems ? I am suspecting it perform a bit slowly that for example
ext4
