what's the reason for low speedup on windows operating system? about psvm HOT 4 OPEN

Hi William,

For you problem, the problem size is too small.
If the dataset could be larger, most time will be spent on the step E = I + H^T 
* D *
H and this step could archive good speedup. For small dataset, time is mostly 
spent
on other steps (such as CF: cholesky factorization) and in this case, the 
speedup is low.

Thanks. Let me have a try on larger dataset.
Rcv1 dataset is selected to test it.

Hi, 
After do some large dataset, i found the psvm is a large memory-consuming code 
during the ICF 
period.The RCV1 and ijcnn1 dataset are tested on my cluster. The result is not 
so well.
