[higgins-dev] createPersonalRequest performance problem 
Hi Mike,

We are trying to improve performance of our web based identity
selector and right now the biggest problem we have is with the
performance of TokenRequestFactory.createPersonalRequest sts method.

It looks like single call to this method may take up to 40 seconds!
And about 99% of this time is taken by key pair generation method.

I was looking at the implementation and it looks like it follows MS
specification precisely and I have no idea how it could be improved.

Do you have any ideas how to improve the performance of
TokenRequestFactory.createPersonalRequest sts method?

-- 
Thanks,

Valery
