unRAID recommended memory

In my quest to find a replacement for my failing Drobo, I'm setting up a few different boxes to test out performance. Right now, I'm playing with unRAID (latest beta).
I'm copying 1.38TB to it - and it is slow. The system it's in is not a super powerful system, so I'm not expecting the world. It's running in an Athlon II X2 250 with 4 gigs of RAM. I have a 3TB drive (parity), a 1 TB and a 1.5TB right now (free version).

The web UI is showing it pegging out the 4GB of RAM. If I increase the memory, any idea if I would get better performance?
This system takes DDR3 so I could buy an 8GB kit for about $70. That'd give this system 12gb ram. Just curious what other people are using.

Running the top command, the processes smbd and shfs are using the most resources. (Which makes sense as I'm using Samba to copy the files from Windows to the unRAID server.)

I won't normally be copying this much data to the system. Migrating some of the data over to test out Plex from it later.
 
Again I recommend SnapRAID. My core2quad on my linux based pvr (also has the storage) usually syncs at between 100 to 300MB/s for my 6 data disks (a mix of 2TB and 4TB drives from Seagate, WDC, Hiatchi and Samsung) and with dual parity (two external 4 TB hgst touro drives). I have 6 GB of ram on the core2quad. Currently it needs around 1GB of memory when doing the sync (which I do about 1 time per week).
 
drescherjm - I'm setting up SnapRAID in my Ubuntu box as well. It's a core2duo with 6 gb so we will see how it goes.
I wanted to try out a few solutions before moving forward with one. I really am not impressed with how slow the unRAID system is right now. Considering I have to get another 4-5 TB copied from my Drobo, I'm looking at a huge amount of time. (Again, will not be doing this much syncing under normal circumstances.)
I'll share my findings once I get it set up. (My dishwasher decided to break, so am kind of bogged down. Everything seems to happen at the same time in my house!)
