Reason of some people is what they see !
I'm not going to force you believe me but the below story is a real story and For me it does not matter you guys believe that or not !
The story :
I always rent rig from beta rigs !
Two days ago i rented two rigs : One of them was 10 MH/s scrypt and another one was 110 Mh/s x11 .
And these are graphs .
In picture 1 :
From start to 11:20 the rig was mining on wafflepool and it's showing average of hashrate is 75-80 MH/s .
I thought the rig has problem then i switched to Multicoin on dedicatedpool.com from 11:20 to 13:15 and saw the rig is okay and average hashrate is 103 Mgh/s
Again i switched to waffepool but this time to another server eu.wafflepool.com:3331 by d=1.28 password and saw again hashrates down to 65-70Mh that is a little larger than 25% stealing hashrates .
After that i was sure waffepool stealing hashrates i switched to dediclatepool until ends of rental time .
In picture 2 :
Form start to end i was minig on wafflepool scrypt algortim and the pictrue is showing average hashrate is 8 MH/s .
During all time graphs and 15min approximated in the wafflepool was showing 10 Mh/s and 110 mh/s .
Sorry for my english but waffepool is really scammer.
So, there's a very easily explanation here, and it has nothing to do with me "stealing hashes" (seriously, really?). Most likely, since it is a rented rig, and the person is getting paid for only the raw hashing power, they've most likely tweaked it waaaaay over the top in terms of performance. Which is normally fine if you're mining the same work for a few minutes, and then get a new chunk of work.
However, on switching pools, you get new work quite often (depending on a ton of factors, many times it is close to every 5 seconds). If his rig is tuned to the point that it takes it a full second to start doing new work, he'd show he's mining at 100MHs. If he were mining a single coin, or on a pool that doesn't switch very often, he would probably see almost all of that as valid hashrate (1s switch time / 60s work time = ~1.5% rejected). However, if on WP, where we switch every few seconds, you could very easily be seeing 20% rejects (1s switch time / 5s work time = 20% rejected).
Seeing your next post about going to a different server (eu) and seeing hashrate drop even more puts even less doubt in my mind. Since you're now looking at 1s work switch time, and adding easily 300ms (0.3s) of latency to the calculation: 1.3/5 = 26% reject rate.
Thanks for trying to rationalize your way through it instead of immediately jumping to "this guy who has been extremely forthcoming so far, is most likely stealing from everyone", and then putting it in caps, and then in colored bold fonts for everyone to see. I appreciate it, and I'm glad you're happy with the service here.
