jhPrimeminer hyperthread

I am using ypool to mine and they suggest jhPrimeminer. My laptop with I5 cpu having hyperthread and look like much slower mining than my older 2 cores laptop, I guess it is the hyperthread. Should I Just diable the hyperthread of I5 in bios? Or I can set that up in jhPrimeminer?

you should be able to get the best of it by setting number of threads to use, eg if you have 2 cores with hyperthreading it means you can try mining with 4 worker threads
