Not sure if having 3 random generated on top of the six other styles makes it impossible or if MinerD will really do better than the default client which I noticed now shows hash rate since updated.
I tweaked minerd a bit to use the Quark hashing algorithm. I couldn't get it to work quite right, but the hash rates were the same as I got with the wallet. It makes sense since the same hashing code is used in both the wallet and minerd. Minerd is faster for SHA2 because it has lot of highly optimised SHA2 routines.
