The pool seems to be solo mining a lot. The majority of my shares from today have gone into solo mining. Why not put them into eligius or something like that instead?
Solo happens in the following 2 conditions:
* the target pools don't give multiclone enough work quickly enough to distribute to its users to prevent 'miner idle's
* a multiclone user's miner is misbehaving (hasn't been submitting enough valid shares relative to the getworks requested)
That said, for the past ~day, we've only got ~3% stale and ~3% solo.
bash-4.1$ grep "submitting share.*" log/037 | wc -l
101286
bash-4.1$ grep "submitting share.*incorrect" log/037 | wc -l
3215
bash-4.1$ grep "submitting share.*solo" log/037 | wc -l
2998
With a 1.25 efficiency (of the confirmed shares, which is what my new miner has got for the past week since the problems were resolved), you still come out (1-.03-.03)*1.25 = 1.175 -> 17.5% ahead of the 'ideal' non-hopping case.
I have some ideas on things that might help reduce solo that I might get to this weekend...
