This is something I have difficulty understanding. Your mining rig isn't going to run any faster in another pool, and it's definitely going to cost you more to mine somewhere else.
Not necessarily. Eclipse (no I have no connection to them really) does DGM with no fees (but they do keep the tx fees IIRC), and p2pool is no fee as well. Technically it doesn't matter if you mine with a pool or mine solo, your payout over time should be identical. However "time" can be centuries if you mine alone.
That is one question on my mind: Do large pools have any luck advantage because as they generate blocks they have a head start on the next block due to propagation delays? The advantage might be small, but if it's cumulative it could be a problem.
Also a larger pool might have a lower percentage of rejected blocks, it's small but there.
As for fees, neither eclipse or eligius charge fees, however I always seem to have 3% in my "shelved shares", and Eclipse's luck always seems to hover around 47-48%. Actually that might mean a 4-6% less payout, correct?
It makes absolutely no sense to me that anyone would leave, unless you like paying a fee to see pretty numbers and charts. The end result of leaving is you end up with less BTC.
One of the biggest draws of Eligius for me (aside from the trust in the provider) is the stats allow me to match my system performance with what they are seeing. On Eclipse I sometimes see a bit less, and I wonder if that's due to lag, pool quality, or chance. I wish they had longer running stats so I could see what my systems were doing.
What I might do is split my 900+gh between three pools: 300 for Eclipse, 300 for Eligius, 300 for p2pool. Once Eligius comes back to a stable state, if they're having capacity problems I will point my stuff elsewhere even though it costs me a bit in that rock-solid reliability I have grown to trust.
