I'am mining with cudaminer (~137 kh/s), too many "stratum detected new block" messages and 3 accepted shares for 15 minutes... Any recommendations?
No, not really, 3 accepted shares is about average on 512 share difficulty. There's no such thing as too many "stratum detected new block" messages, by the way.
Ok, didn't know the difficulty was that high.
What do you mean by 'There's no such thing as too many "stratum detected new block" messages'?
Some coins are very fast, and there are new blocks like every minute.
CleverMining is a coin-switching pool, so every time it switches a coin, a "new block" will also occur.
