Hashrate for Stratum Lower

[leancuisine]

I have just started mining Litecoins on burnside's pool using stratum, but there is a huge difference in the hash rates from getwork vs. stratum. Using getwork, my hash rate has been 167 kh/s, although 50% stale shares, but with stratum I am only getting 3.6 kh/s with no shares and it does not even show up in my hash rates. I am using Ufasoft 0.58. How can I make my stratum hash rates the same as getwork?
