I've written a Clojure backend for Miniprofiler, using the UI repository (https://github.com/MiniProfiler/ui).
Read more about it here:
And a sample performance debugging session is detailed here:
I've been running Clojure Miniprofiler in production since July 2014, and it's proved both very stable, and extremely useful.
Many thanks to those that have worked on the UI stuff - whilst documentation was relatively sparse, it was pretty easy to get running and use, and it's helped me debug countless performance issues that I wouldn't have even seen otherwise.
