Links to NAS and SAMBA performance

In my prevoius blog I wrote about my tests to increase the read/write speed on my Linux home server, now I will collect some links here:

A very good comparition of Windows and Linux file system for using as a NAS.

Test result for a consumer NAS device.

Test results for Linux file systems (ext2, ext3, Reisser, XFS).

IOZone test suite.

NAS performance measurement comparations.

A test measurement of comparing Solaris ZFS, Ext2 and XFS in NAS environment. It is using NFS intead of SAMBA, but the speed results are very convincing with read speeds over 76 Mbyte/sec and write speeds arround 35 Mbyte/sec.

I started to do some own test in the server itself, and copying a file from one disk to an other was done with the speed of 23,4 Mbyte/sec, which shows, that it is possible to write to an ext3 filesystem with speeds above 20 Mbyte/sec. I will do some more testing later.

I did some testing on my Windows Desktop computer and got a read and write speed of ~90 Mbyte/sec, and this is the benchmark, this is what I am aiming.

The iozone program seems to be a good test program, but if you are interested in the raw filesystem performance you should do the measurements with larger files. I plan to use the following command line:

iozone -Rb result.xls -i0 -i1 -s 4G -r 32M -f [filename to test] -+u
