Smart Cards slow with Sun Ray Windows Connector

I'm succesfully using smart cards to log on to Windows 2003. But the problem is that it's very slow!

If i enter a wrong pin code, its fairly quick to respond with an error but when entering the right one it takes like 13-15 seconds to log on. The smart card slot on Sun Ray 2 is flashing all that time, so it seems like it's reading the certificate takes that long?

Any ideas how to make it quicker?
