CGMiner vs Pool reporting different Kh/s

[LawrenceZA]

Good morning everyone,

Has anyone experienced a difference in what cgminer reports as your kh/s VS your pool stats?
I've got a 5970 running at intensity 13 and cgminer (2.8.2) shows that it's doing 500kh/s but my worker on litecoinpool.org reports on 125kh/s at best.
Anyone seen this before or have some possible solutions?

Thanks,

LawrenceZA

CGminer calculates the shortest interval between hashes and calculates the hashrate from that, pools usually take the average for the last minute and display it. So in essence pools show AVERAGE, CGminer shows MAX.

just tested on POWER4+ cpu and i see little difference... cpuminer 'sha256d' is just a bit faster then cgminer 'c' anyway slower then openssl sha256_ppc routine.
