FreeNAS speeds

[OFaceSIG]

Anyone getting higher than 400Mbps reading from or writing to your FreeNAS boxes?

depends entirely on the hardware, but yes i have seen a setup with freenas as the OS that had read speeds around 570Mbps.

FreeNAS is still based on FreeBSD 7.x and thus it misses the TCP buffer size auto-tuning and other such optimizations.

But there can be many causes for low throughput. First of all, you need to benchmark properly with CrystalDiskMark or AS SSD; not other benchmarks which do raw I/O.

You can also try iperf network bandwidth testing.

How about OpenFiler? Would it fare better ?

That's linux based, i haven't played with it.

FreeNAS 0.8 is built on the newer FreeBSD 8.2 though, so you could test FreeNAS 0.8 as well. And my own ZFSguru project is also based on FreeBSD 8.2/9.0. Both should perform better than FreeNAS 0.7.x.

Your client OS also makes a difference; windows 7 can read faster from samba share than WinXP can because it supports async I/O.

yeah I've ordered 2 2TB drives to rebuild that server in my sig with FreeNAS 8. That other post of 570Mbps is making me drool.
