I’ve looked from time to time, and Bitcoin invariably gets exactly 50% of CPU, even when System Idle Process is getting the other 50%. I assumed this was set, and had it in mind to ask you whether the setting could be changed so that Bitcoin could be given its head (e.g. overnight).

Do you have a dual core system, such as a Core 2 Duo? Bitcoin currently only launches one process to generate coins but it could easily launch one for each processor. It’s probably about time I implemented that.

I have a Hewlett-Packard HP Compaq dc5750 Microtower with an AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ 2.19 GHz, 1.87 GB of RAM

So it looks as though I could run more processes; and it may be that Bitcoin is getting 100% of half the available CPU.
