    Hi Steve,

    We have just completed a period of testing using OmniOS 151026, having as reference our legacy platform, FreeBSD 11.2-RELEASE.

    Test was done using exact same hardware, mainly on a simple 8-disk RAID-Z2.

    I/O throughput was comparable.

    Did you test using r151026 as well?

    I saw you opened a ticket, which is probably the favourite way.
