As would I - I've used YourKit a bit but the results can often be pretty impenetrable. Also, knowing how to interpret results specifically for Clojure would be great too. Jonathon, if you're specifically interested in memory, check out Eclipse MAT - it's a great, free tool for analysing heap dumps

YourKit has the ability to take memory snapshots then analyze those snapshots to find retention paths. So it'll help you see things like "500MB of data is held by this single reference". Getting up-to-speed on YourKit isn't bad if you're familiar with profilers. If not...maybe try learning it anyw

I have some time constraints, and need to figure out why an import script is hogging so much memory and crapping out on Heroku. What tools would you recommend that would (a) give useful information for tuning and (b) have a short learning curve? -- You received this message because you are su
