p2coins.com:9332 has 81% effie

Very bad node.
Thank's rav3n_pl for fast reply!!!
I'm looking for some node in europe with good latency and efficiency ... could you recommend one, possibly with 0% fee?
PS i've switched to
http://pool.petamine.co:9332/ is this a good pool?
Check
http://p2pool-nodes.info/M
I found the pool petamine looking at ttp: //p2pool-nodes.info/ and I chose it for the lowest ping.
after a couple of hours my reward was lowered again from 0.0088 to 0.0058 ... very bad for 1.5th / s.
my antminer were set with the share diff 256 (I tried 512 but I had worst results).
I'm doing something wrong or am I just unlucky? ;-)
again thanks in advance, Erik
Difficulty is very high. It's hard to get a share in with 1.5TH/s. It took me 12 hours to get one share with 1.1 TH/s.
Remember the 3 days PPLNS. Your payout dropped because some of your shares from 3+ days ago have fallen off.
