We have an issue with our admin site on ML9.0.1.3. It seems that it can't handle the amount of registered customers. The site actually times out for some users. The session takes to long to sign in. As a test I cleared out all of our customers in one of our beta server's database and the site functions very fast.

We only have 50K registered customers. This isn't enough to bring the site to a crawl. Is there a patch to fix this?
