This lightning talk will explore some performance problems we discovered while diagnosing a memory leak in a JavaScript application, and how we fixed them to make JavaScript memory analysis faster than ever. We'll discuss the steps we took to achieve a 100x boost in speed to Heap Snapshot generation in collaboration with Igalia. The result: we reduced the time it took to capture a 100MB heap snapshot from a painful 10 minutes to a very pleasant 6 seconds!
