I've installed sysbench latest version from ports which is 0.4.12_1. Having run the standard oltp both read only and read + write it doesn't seem like a very good benchmark for disk as it seems like it does very little disk access. == ZFS == Test execution summary: total time: 248.5637s total number of events: 1000468 total time taken by event execution: 3968.4764 == UFS == Test execution summary: total time: 220.7406s total number of events: 1000588 total time taken by event execution: 3523.5829 I noticed that UFS's support for TRIM is very poor compared to ZFS's with it queuing all TRIMs till after the test completed as well as performing many more BIO_DELETE requests causing significant system overhead and disk saturation after completion.
