Not really. The more hash rate at the pool, the LESS you get paid.
About 2PH or under is perfectly fine.
Who cares about getting paid daily if it's more than it would be at any other place?
No, there is no clear point where the higher hash rate would be noticeably detrimental.
Obviously as the hash rate goes up, the number of rewards you get increases, but the amount per rewards decreases.
They have an expected net zero effect on total rewards.
The only certain affect of a higher hash rate is an average slower block change time for miners, due to more miner connections, however that overall affect is very small with ckpool.
As we know, the main pool server is able to handle over 5PHs without any trouble as we saw back in January.
The ckpool software is able to process work and block changes very fast, certainly faster than any pool that isn't doing SPV mining, and provably faster than the pools that do zero txn verified blocks, so the effect of a higher hash rate isn't really relevant when compared to most other pools.
