I tried to google this first, can't search forum as it not working so please dont hit me

On some pools my two gaw miners (1.2mh/s each) get full hashrate (third figure on bfgminer so its accepted hashrate) like multipool.us
BUt today i have been playing around different coins like gold, audio etc and with other pools my hashrate accepted by pool is very low.
I mean instead of having 1.2mh/s per miner i get 300-600kh/s if lucky. Now mining audiocoin at 150kh/s !!
Why is that? does it mean I'm only minining at 150kh/s??
Bfgminer figures:
1.34 / 1.34 / 0.13Mh/s
Am I doing something wrong?
