Great link
iozone's syntax can be a little challenging. What I typically do is write a bunch of commands in a text editor depending on what I want to test and what options I want to use, and then copy and paste into the windows shell.
Remote test locations have to be mapped / mounted for iozone to work (ie, Windows needs to see them as a letter, drive "G" or whatever).
Make sure you test file sizes above and beyond your system RAM - this will eliminate all cache effects and show you what your disk subsystems are really capable of.
iozone is somewhat depressing - I had no idea how difficult (expensive) it would be to hit/break 100MB/s over gigabit. The expense killed this project for me.
In the end, my ubuntu server "NAS" is satisfactory considering how little I spent (mid to high 60's MB/s using NFS and 40-50 MB/s using SMB between other linux and Win XP clients). That's for file sizes in excess of 2 GB (HD media for example).
You should also test the limits of your network & switch. You can use jperf (http://code.google.com/p/xjperf/), which is the GUI version of iperf. For example, my gigabit stuff at home peaks out at about 950 Mb/s between any 2 nodes. That's a straight TCP stream between 2 transceivers - you'll probably never hit that with any file transfers or anything that uses any higher level protocols. But it'll let you know if anything in between your PC's and your NAS is holding you back.
