92,5% efficiency vs 70% on blastbob's pools

(sorry blastbob, but I wanted to try others P2Pools

)
Payouts are coming like everywhere else (few missed block, but no one can explain why...)
I'm satisfied.
My hashrating is 370Kh/s and i get 0.20 of reward... I got a lot of messages like this "Stratum from pool 0 requested work restart"... when I minned LTC i never got that message... what is happened?
This msg appears when a block is found on the network, so your miner have to start working on a new block. It's caused by a very fast block solving, which is not the case of LTC/BTC.
