Verbatime is for development. Run it on your machine to check the performance of a feature you built, not in production.

Why#

To see where one request, one server startup, or one batch job spent its time, you need every call it made, in order. A sampling profiler only sees some of them, and most other profilers merge all requests into one average.

Verbatime records every call and shows it as it happened.

• Every call. Each run of a method you choose becomes one call tree, with the order and time of every call in it. Nothing is sampled or dropped.
• Drop in. Add one -javaagent flag. No code changes.
• Cheap. A recorded call costs about 35 ns.
• Large recordings. 100 million calls open smoothly.
