Interesting, never knew this... But can one windows machine run multiple Slush proxies? I never had success opening two, only tried one time thinking it might distribute work evenly. I checked the thread you linked and saw what looked like scary Linux stuff, is that the only way?
No, that link is for how to set up pool server software. Yes, you can definitely set up multiple proxies on a windows machine. Just open up another command window and make sure to assign a different getwork port to each proxy.
I'm not very skilled with writing .bat files, I know how to do it for bfgminer, but not Slush's Proxy tool. Can you paste a sample of what this might look like? I thought Slush's tool only worked on 8332...
Edit: Okay, I got a .bat file written that launches it, and it seems the port switch is "-p", but I can't seem to get it to talk to Slush's server. Is there a way to run stratum proxy for Slush but use a port other than 8332?
Right now both blades are running on 1 proxy, using port 8332. I've got the .bat file halfway there, it opens but can't connect...
