Please note I didn't ask "what matches my workload" or "please
architect my setup for me" :P Mainly I just wanted something for a
couple basic sanity checks that hardware is performing in the general
ballpark of what it should, that there weren't any pathological issues
w/ the drivers under SmartOS. Secondarily would be something that can
run under native, LX, and KVM to compare relative overheads, and to
compare against the same hardware running, say Ubuntu Server or
CentOS. If it were something that there was a public database to
compare against, that would be a bonus.
I stand by my initial reply :)
There really are too many variables to offer a generic solution. One
obvious example is comparing lx-brand zone with KVM on a pool without
decent log devices. Disk benchmarks will be shite in the KVM, but if
the same setup had a log, things would be much closer (zones would still
win!).
If I want a quick and dirty comparison, I use bonnie++ (or CrystalMark
on a Windows KVM) and building gcc. The latter is a surprisingly good
test; it will stress various aspects of your machine and has shown up
numerous performance issues over the years. The single character write
numbers from bonnie++ are pretty meaningless on ZFS.
FWIW, the main production workload that I will care about is a
not-well threaded java server app, so single-threaded performance,
coupled with a large-ish MySQL DB with frequent, random I/O both read
and write.
bonnie++ and building gcc (both can be single or multi-threaded) should
give you some decent comparisons.
