Is there a suite/script/configs for benchmarks that have emerged as

I/O, and would like to compare native linux hardware RAID vs MD RAID,
and Native zone hardware RAID vs. ZFS (without and with SLOG).
This is a classic "it depends" question. The only reliable benchmark is
one close to your actual workload. You should be building your ZFS pool
to match.
In my case, my of my systems are in build farms, so I use database
benchmarks along with building a representative project (or gcc).
Ideally (time permitting) would want to test comparing native, LX
zone, and KVM. Anyone have ballpark figures of the performance
overhead those respective types, ideally of the various subsystems?
(Disk, CPU, network, memory)
Again, it depends what you are doing. LX is much kinder on the hardware
and will have better I/O, but there are corners where KVM will still be
faster.
