Without clustering MySQL like I have clustered pushpool/namecoin/bitcoin there is no way that I know of I can accept shares faster than 25 GHs without problems.
If anyone has any suggestions that will be quick to implement I'm all ears.
Just to be clear i was in no way complaining! I was just checking that I had understood things properly and that i wasnt doing anything wrong and loosing shares!
Are you running MySQL inside a traditional amazon EC2 compute instance? Or are you using the Amazon Relational Database Service?
