Just recently upgraded my network to gigabit (Netgear GS105 + brand new CAT6 cables). Previous to my upgrade I was maxing out my 100Mbit network from the NASLite with constant 11MB/s transfers. The 3Com 3C905 in the NASLite box was replaced with an Intel PRO/1000 MT adapter and a Netgear GA311 was installed in the client machine. These are the numbers I'm getting after the upgrade:

I'm not exactly thrilled with the performance "boost", was I expecting too much? See my signature for specs on the NASLite machine.. any ideas of possible causes of this semi-dissapointing performance increase?

(got a suitable iozone command line ready?) It should however be noted that Im getting 22MB/s read/write using FTP but I'd like to identify the bottleneck in my system. The drives alone should be able to pump out at least twice these numbers, is the PCI bus the bottleneck here? I was under the impression the PCI throughput was 128MB/s in theory but having to share the LSI card as well as the gbnic might be causing it to hog down? Any help is greatly appriciated!
