setting pool difficulty

[heartofalion]

Posted this in the newbies section and they directed me here.

I am currently mining in a pool that lets me set the difficulty for my workers (16-512) i am mining a scrypt based coin at 3MH/s a second.

My question is how to i determine what to set the difficulty at and what exactly does it do?

Thanks!

the difficulty affects how many shares you send
eg with low hashrate sending 3x32 dif shares would give you more than sending 1x64 diff share
but if your hashrate is high you wont want to trip over yourself sending low difficulty shares
you might send 60x32 diff shares a min when 20x128 diff shares a min would give you more

In p2pool you can set the difficulty adding to your wallet address next items:
