I just upgraded my V2 Snap 2000 to 256 MB ram from the original 64.

I did an informal testing, and it doesn't seem to make any difference for the transfer rate of many large (~4-6 MB each) files. I use my Snap primarily for hosting my .mp3 files, with iTunes running on any of several client machines.

To test the transfer rate, I copied a folder containing about 300 files (totalling about 1.5GB) from the Snap to my desktop PC. The lan consists of a Netgear WGR614 router and a 100mbs NIC in my desktop PC. Regardless of whether I have 64MB, 128 MB or 256 MB in the Snap, I get a transfer rate of about 4.5MB/sec.

Likewise, when I copy from the desktop machine to the snap, I get a transfer rate of about 2.9 MB/sec, regardless of how much ram is in the Snap.

The additional ram might help more with speeding up repetitive access to the same data, since more data is probably cached.

I only get about 1.3 MB/sec from the Snap to my notebook with Wireless G. Nevertheless, I have no problems hosting MP3s on the Snap for iTunes over the wireless network. In fact, I can run iTunes on my notebook, with the MP3s on the Snap, and stream the audio wirelessly to an Airport Express without any glitches. It actually kind of amazes me, it works so well. I can even store .iso files of DVDs on the Snap, and play them through the Wireless network on my notebook without any jitter or dropouts.
