We use FreeBSD 9.0 as a NFS server for our ESXi 5 servers. We added a ZIL/SLOG device to our setup and speeds are back to normal. The slowdown is because the async and sync behaviour of ZFS and ESXi.
One other option is to disable sync on the ZFS dataset. That will also speedup NFS transfer speeds for the ESXi hosts, but then there is a slight window for data corruption in case of a sudden crash of the server. regards Johan _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
