Hey again, 

We recommend the latest version of FishEye for the most recent improvements in performance. I cannot guarantee this will solve your performance issue as there are many reasons why this can happen. Just to name a few: poorly configured repository/ global settings, recourses limitations, disk speed, large revisions/ files, etc. We recommend our customers thoroughly understand the following articles to make the most of the application. 

• Tuning FishEye performance
• Improve FishEye scan performance
• Best practices for FishEye configuration
• How FishEye uses memory

If none of these help you, please raise a request at https://support.atlassian.com/ if you have a support license and attach a support zip and 6 thread dumps taken 10 seconds apart during a slow period.

At the time of writing, 4.5.3 is your best option.

For new features, have a look at the release notes.  https://confluence.atlassian.com/fisheye/fisheye-releases-298976966.html

As for "fast enough", there's no way to know until you test it with your data.  There are performance improvements in the later versions, but whether they're going to help you specifically, we simply can't tell.
