Benchmark of FreeNAS 0.7, a single SSD and AFP

June 26th, 2009

Harryd has bought a solid state drive and is testing it with FreeNAS.

He has done some FreeNAS performance testing using the SSD on his Intel Core2Quad Q6000 (2.4 GHz) based server with 8GB is RAM and gigabit Ethernet. The testing is done using Iozone which is used to benchmark filesystems.

Initial tests showed speeds of just 60 MB/s read an 80MB/s write which is low compared to the drive’s capability. Harryd identified the problem was his Gigabit switch and so connected the FreeNAS directly to his Mac Book Pro.

With the direct connection he was able to achieve a constant bandwidth of 77 MByte/s write and 105 MByte/s read performance.

This highlights a something I noted in my book Learning FreeNAS. If you don’t have the right network equipment it doesn’t matter how fast your FreeNAS server is, you just can’t get the results over the network at the best possible speeds. This is especially true with Gigabit and many home/consumer switches don’t have a high throughput.

    Harrdy, It is always a pleasure… the more exposure FreeNAS gets and competent engineers (as yourself) get the better.

    Regards, Gary.
