Non safepoints biased Java profiling

Post by vektory »

Hello all,

A few mons ago Andrei Pangin has published a nice async-profiler (https://github.com/jvm-profiling-tools/async-profiler), that can profile without safepoint biases. It's would be very cool to support such profiling directly in YourKit.

Materials from his presentation on JPoint 1017, Moskow: http://assets.contentful.com/oxjq45e8il ... filing.pdf

Thanks.

Hi,

I would also be very interested in an answer to this thread. Is this something that Yorkit is working on? The safepoint bias is a real issue, and I find myself using async-profiler almost exclusively (but I miss YourKit's nice UI).
