cmc marketmaker and system performance

When running marketmaker and webiress together my pc slows down to the point of being almost unworkable. It's not a great system but there must be a better way.

Saw that IG use a browser based system which I assume reduces this issue somewhat. Do people that use IG and webiress have any problems with system speed?

Might just close my cmc account and move over to IG but thought I'd see if anyone else had come accross the same issue first.

Cheers.
