Something I noticed; when using phoenix 2 beta which supports rollntime, eligius makes the miner roll time a lot, which is good. bonuspool however is -always- sending new work, probably giving the server unnecessary load. just a thought.
Heya
We do actually make use of rollntime, you will notice every now and then nrolltime entry (phoenix displays it nicely, not sure bout other miners), also serverload is the last of our concerns considering we are running on a utterly underused monster server:
2x Xeon X5650
48GB DDR3 ECC
4x2TB SAS 15000 RPM RAID 10 drive (data storage)
2x120GB SSD drives (caching and memory fast-fetch usage)
And some other tit-bits.
That said stale percentage is plummeting share by share, damn happy about some success finally.
