hy to everyone,
I'm mining from 2 weeks with 10 asic erupters. I'm trying to collect some info about correct configuration about my hw and deepbit portal. Now as now I'm using RaspPi with MinePeon (for 8 asics) and an old Epia pc (for 2 asics).

Some things I'm not understand clearly...
Is there a logical reason when it is convenient to use Proportional or PPS? It may be influenced about how many Ghs I use?

A reason for this question is about last automatic transaction. Now I'm using PPS and last transaction is not recognised by the network. Is there a reason? The link reported on DeepBit is  https://blockexplorer.com/tx/5ac6d1a49cd8ad0dc1251659336df6553f290342f4d52725e18cd58c942f6911 in data 18-11-2013.
Is there someone with technical info that may explain me where is the problem? I don't think a Ddos may be the cause... Is my opinion right?

Thank you for your patience.

I'm waiting 2 blade 10Ghs...
