[OpenIndiana-discuss] OpenSolaris vs OpenIndiana Benchmarks

[Matt Breitbach]

New to the list - just wondered if anyone had any input on some of the
benchmarks that I've been running on OpenIndiana vs OpenSolaris.

We tested OpenSolaris b134 vs OpenIndiana b147, and got some interesting
results.  It looks like the random write performance has decreased, but some
of the read operations have increased.  Have there been any significant
changes to ZFS between those builds that would cause the performance shift
we've seen?
