I also had some similar experience with HT whereby my F90 application using OpenMP ran ~10% slower. However, after reworking the code for problems other than HT issues I re-ran a performance test of the OpenMP F90 application and now find a 23% improvement in the runtimes.
Since then I've migrated from a P4 530 single core with HT to a dual processor dual core/processor system (4 cores) no HT. Running much better now.
