compare-jfr

Compares two JVM profiles held by a running Jeffrey Microscope — a before and an after — using differential flamegraphs, to answer whether a change made the application slower, faster, or allocate more. Use whenever the user asks if a change regressed performance, what got slower or faster between two runs, to compare two recordings, benchmarks or branches, or mentions a baseline, a before/after or a performance regression. For a single profile, analyze-jfr applies instead; for a heap dump, analyze-heap.
