Are you doing PPS or proportional?

Proportional can introduce a lot of variance. As the total number of shares increases your proportion is smaller and smaller, especially if the pool has been "unlucky".

But the more plausible cause is this: http://bitcoin.sipa.be/speed-lin-10k.png

Hello,

I set up my first test miner on the DeepBit pool a couple of days ago.

It's a lousy old GPU that can't even churn out 100MH, but it's enough to aid me through my learning process.

To the point: I've received a couple of minor auto-payments and the last one is sitting unconfirmed for quite a while. Is this normal? Have others experienced huge confirmation delays?

The receiving node is 1BgftNug4HRCvVUeaTjJtNjP1EiGKVKgHe

Thank you
