Pseudo share doesnt affect in founding block anyotherway than it restarts works everytime that changes, so selecting constant could help abit keeping miner busy. Large miners should use bigger sharedifficulty - that would help poolwide. Like btcaddress+501/100000000, then there should be less 5 s restart times, and big miners earn that way more too. Ckolivas proxy helps keeping miners busy also, I have got very good results with it in p2pool and solo pool, it squeezes juice out of miners, with s3s mindiff and startdiff have to be chosen so that you can see best share..
Last weeks bests with 2th= 2,347,645,293, one ~1,500000000, 537,352,921 .. newer got those kind of results without proxy.
S3:s doesnt show best share with all share diff + 512, 1024, 4096 doesnt show, 500, 4000 ... it shows
nohup ./ckpool -p -A -k> /dev/null 2>&1 &
Wondering how ants would perform if those are turned to diskless nodes and booted with tftp, that way cgminer could be running on some more powerfull machine, i think s2 s3 s4 are suffering constan restarts - the mainoboard doesnt have enough power. And that way I doesnt have to wait new firmware and cgminer...
