STS 3.1 JSP editor lag

[Skel625]

Is anyone seeing the really bad lag when opening/viewing JSP files? Average is about a 5-7 second lag before the file opens/renders. It is so bad we are preparing to roll back to an earlier version of STS. We were using 2.9.2 and were not seeing any issues like this.

Anyone encountered it and know a solution (other than switching to text editor instead of using the JSP editor which is not an acceptable solution)??
