Hello everybody,
hope this is not a totally noob question, but I can't answer this myself.
I have experimented somewhat with CPU mining. Using my own computer with Intel Core 2 Duo I get about 10-15 kH/s per CPU. Using a cloud server (Windows Azure, AMD Opteron 4171) I get 700-800 kH/s per CPU.
I ran Sisoft's Sandra Crypto benchmark on both systems and found that my cores have about half the processing power of Azure's, but that's a far cry from the >50x mining performance gulf I witnessed.
The only difference is that I have Windows on my desktop PC while I used Ubuntu on the cloud server. Don't believe the difference boils down to that though.
Anyone care to explain what's going on?
Thanks
