mikaelh has been hard at work optimizing the code (10 new commits on bitbucket)

After an hour running this on mainnet I'm seeing consistently higher pps and chainspermin than with hp7 on an identical box

I think it's time for another round of donations to keep mikaelh going

How much higher are you seeing? I would donate in primecoin now but I only mined my first block yesterday and it still is immature - it's going to be at least another day before I am able to use the coins.

Current mining info from the box compiled from the latest code:

Code:

{
   "blocks" : 81661,
   "chainspermin" : 10,
   "currentblocksize" : 10284,
   "currentblocktx" : 1,
   "difficulty" : 9.26995111,
   "errors" : "",
   "generate" : true,
   "genproclimit" : -1,
   "primespersec" : 2995,
   "pooledtx" : 1,
   "sievepercentage" : 11,
   "sievesize" : 4400000,
   "testnet" : false
}

and mining info from the box running hp7:

Code:

{
   "blocks" : 81663,
   "chainspermin" : 7,
   "currentblocksize" : 1000,
   "currentblocktx" : 0,
   "difficulty" : 9.26969045,
   "errors" : "",
   "generate" : true,
   "genproclimit" : -1,
   "primespersec" : 2010,
   "pooledtx" : 0,
   "sievepercentage" : 11,
   "sievesize" : 4400000,
   "testnet" : false
}

PPS and CPM fluctuate on both boxes, but the newest code is performing ~30% better based on the stats. It's hard to tell what improvement this would translate to in finding blocks.

I'm wary of comparisons between testnet and mainnet - due to the difference in difficulty, some optimizations might never get used on testnet while they are in constant use in mainnet because of the higher difficulty.
