so waited a few blocks more and seems that my 200 hpm is getting 60 hmp on the pool and making almost 1 MMC from 20 servers (32 cores/server)
Going to give it around 10-15 minutes more, if it stays the same going back to xpool.
Update:
HPM on the site is going down, lol sorry but I lost trust in this pool. if the stats are correct then the 1200 HPM miner must have a 1000 servers running.
Back to xpool.
I trust this, I just imagine its a botnet. If it is a botnet that is approx 6000 bots which is quite easy to get...
I also think it's from a botnet. If you compare the graph from http://agran.net/memorycoin2_calc.html about the difficulty it was raising maybe of one ore more botnets.
It still is quite possible for a person to achieve that kind of speed on EC2, even with a fairly high reject rate. Remember that the higher reject rate doesn't affect faster machines as much as they spend less time on a hash before looking up and acquiring new work.
Currently I'm getting 9.5 - 9.8 hpm on cc2.8xlarge instance, so this would be more than 100 instances.. 5-7 accounts with 2 regions each x10 instances in each region?
You can request up to 100 of the high-memory (250GB RAM) which has 32 cores (16 physical) per region, although that many never get filled, not even close. However, with just one account, raised limits, and a willingness to pay a pretty penny, it's more than possible. I ran at 900 for a few hours on EC2 until the pool started getting laggy, sending some rejects, and most importantly not providing work fast enough, leaving the miners only using 30-50% of the possible CPU time
