Does anybody know what sort of hardware makes these waves (http://ethpool.org/miners/ae5ba84c7a77d337bc0223cfdf2ca7e836881435)? It occurs in equal 2 hour intervals, goes very high in peaks, up to 0.5 TH/s, but averaging at around 150 GH/s. Since this it ethereum mining, I wonder if maybe somebody made some kind of dedicated machine for this. Otherwise, to achieve that average (not the high peaks), you need around 5-7000 graphic cards. And what makes those waves? Somebody turning another 15.000 cards on and off in equal 2 hour intervals?

Pool statistics are not 100% accurate so there will be many factors involved... doesn't look bad to me though.

With all do respect, I think I have a pretty good picture of how the pool statistics work and what it shows. Something is fishy there, no doubt about it.

to me this seems like a rental service like nicehash:

- 2 connected workers, all the time
- big hash, but not continuous (others taking over your hash with higher priced orders)

ofc it could be other things as well

 The waves are NOT equal.
 They looks like someone pointing Nicehash hashrate at that pool.

The waves are petty regular, don't usually see that from Nicehash. Maybe some other rental
with a schedule.

It is probably either rental hashrate as others have suggested or even a large farm pointing its hashrate at the most lucrative coin or pool at any given time. I have heard some of the largest farms use proprietary algorithms to real-time calculate the best use of their hash-power.

Since their huge hashrates allow them to mine enough coins in a short enough time-frame, say 1 hour to mine a sizeable amount of coins to exchange say ~4 ETH/hr, they can employ mining and trading strategies that wouldn't make sense for most smaller miners who might only get paid once per day or even once per every few days.
