Clojure performance measuring

[Jonathon McKitrick]

If I cannot get New Relic to work, I'm going to stick to my development platform for initial optimization and memory troubleshooting.

What tools do you recommend for profiling memory under Clojure?  I didn't have much luck with VisualVM, since my Mac is a bit dated at this point, but I'd be willing to try again with a decent tutorial.

We've found YourKit (a commercial product) to be helpful.

Try VisualVM. https://visualvm.java.net/

Does it help profile SQL calls as well?

Even though New Relic works best when used with a supported server/container, you'll still get some basic JVM stats like memory out of it. Other than that you could also take a look metrics (https://github.com/codahale/metrics) as it has JVM instrumentation in place and push the data to Graphite, Librato or Datadog.

That said, initial optimization probably makes most sense with tools like VisualVM and YourKit.

Not really - at least not for what you presumably want to do. If you want to stick with NewRelic you could have a look at their custom instrumentation: https://newrelic.com/docs/java/custom-instrumentation-with-the-java-agent); otherwise I'd use something like metrics, ostrich and instrument the calls myself (and most certainly their contexts).
