Tomcat Version: 9.0.81
OS: Windows Server 2016

We recently patched one of our QA servers to test 9.0.81 and ran into 
performance issues.  Page loads that normally take 1-2 seconds are now taking 
50-60 seconds.  We were finally able to narrow the issue down to the SSL 
connector.  Adding an HTTP connector and bypassing ssl resolves the performance 
issue.  We have also tested rolling back to 9.0.80 with the same configuration 
and verified the issue does not exist.

This was due to a regression introduced in 9.0.81, as noted here:

The problem has been fixed in 9.0.82 which is currently being voted on; release 
will likely occur in another day or two.
