I'm not sure if this is a TerraMiner problem or a cgminer problem, but I'm sure Cointerra would be likely to blame cgminer if they can, so I thought I'd start with a wider audience.
I have a TerraMiner IV which underperforms as promised delivering about 1.6 TH/s. _If_ I'm running the included cgminer (4.1.0) in failover mode. So, to one pool, it works fine.
However, if I define multiple pools, and use load-balance (after fixing the syntax error CoinTerra's web interface puts in the cgminer.conf file), then I'm seeing only about 1.2 TH/s reported. If I look at the cgminer log file, it often shows more like 1.3-1.4 TH/s average, but it too shows over 1.6 TH/s when running in failover mode.
Is this a normal thing for cgminer, for the [reported] H/s to be lower when running in load-balance mode?
Thanks...
