What is the obsession with Dwarfpool? I don't get it. It's a cool pool and all, but how is it so much better than the rest? It just had stratum issues and downtime.
http://jpc.hashatme.com could really use some more hash guys, it's an 8CPU, 8GB RAM, 1GBit Internet connected server with RAID-10 SSD, so performance should be great and reliability has been 100% for months. Spread the has around a bit, come mine at
Hash@Me 
BTW congrats to Germany on the World Cup victory!
I personally mine on 3 different pools on JPC ( including yours ) I just feel like it give more chance at a jackpot share even if lower than if i left it all on the same but i think it evens out.
And the dwarves have been a good pool for a long time. And yes only having to put your wallet and not having to setup an account is a plus.
You also have higher fees than dwarf or miningpoolhub ( i don't like their pools but .. ) can explain in part why more stay over these two aside from their bigger hashrates.
