Next I copied over the default "config.json" to the xmrig build folder and edited it for the pool and user info.
Now instead of typing in one long command , ./xmrig -o poolinfo -u username -p pw , I just type in ./xmrig.
I will definitely install this on my other machines this weekend if it does ok on this one machine.
It is VERY easy to install, only problem is i'll need to add some ram temporarily to my two open computer servers that are only running 2 one gig sticks of ram each since I do not think it will compile with only two gigs of ram.
Also I do not know how well the auto config works on newer cpu's.
FWIW, I have been testing a few different setups lately, and read your post. I think you could get a bit better here. I was able to get 560 H/s out of dual 2620's.

For whatever reason, here's what I found to be most successful with xmr-stak
