Blackberry: https is VERY slow

My app connects to a .NET web service via KSoap2 library. When I'm using HttpConnection everything works great and is very fast. However, when i switch to HttpsConnection the app slows down to a crawl and freezes up th开发者_Go百科e phone. This happens when making soap calls as well as downloading files from my app. I know that https is always going to be slower than http, but it shouldn't take minutes to make a simple call that normally takes a fraction of a second.

Has anyone seen this issue before? Anything i can do about it?

Thanks

How much data are you passing in the request/response? I haven't noticed SSL to be any slower than regular HTTP in our app - but those are relatively small requests (several kilobytes at most).
