oh and guys, you can use the normal poclbm with this pool so if that is suppose to give you better performance, why can't we just use that?
The modified poclbm does not give you better performance -- more hashes per second -- nor does it find more shares than the unmodified.
Let me check to make sure I'm understanding this right:
Both clients do approximately the same in terms of mining
The modified client significantly reduces the load on the server
A reduced load on the server allows more users to join the pool
Is the pool remotely near capacity? If not, then it makes zero difference.
