As I have a number of different mining hardware I decided to make some practical comparison of mining pools.

So I get two antMiners 180Gh each and pointed one of them to BTCGuild and other to p2pool node. Initial results of mining (180Gh) for period:
from 1 January till 14 January 2014: p2pool - BTC0.952269785 VS btcguild (PPS) - BTC0.77025336

Now is running continuous benchmark  6 antminers total 1080Gh on each pool:

Benchmark is goin on:
1080GH = 6 x AntMiners pointed to p2pool node - benchmark is running on Elizium node
1080GH = 6 x antMiners to Eligius.st
1080GH = 6 x antMiners to btcguild
