Question : Access to OWA 2010 is very slow

After having configured an http re-direct on a Server 2008 R2 VM running Exchange 2010 I can no longer log in using OWA. the initial page load of the login screen is very slow (e.g. 10-20 seconds). After entering a user name and password the page just goes into a persistant loading state. Prior to configuring the http redirect there was some slowness when using OWA, but now it is unusable. To configure the http re-direct I used the following article http://briandesmond.com/blog/redirecting-owa-urls-in-exchange-2010/.

I'm not sure if there is a connection between the unresponsiveness and the http re-direct as it is just as slow when going directly to the https:// address directly.

The server is running Server 2008 R2 and is running as a VM in Hyper-V. There are no errors in the event log.

I have heard some people comment that there is a known issue with OWA 2010 and slow access, which will be addressed in SP1, but in the meantime perhaps there is something I can do to repair this.

Thank you,
