Running `tests/catch_postcondition` with the JVM backend takes 24s on my machine, 93% of this time is spent during DFA.

Flamegraph consumes [bpftrace](https://github.com/brendangregg/FlameGraph/blob/master/stackcollapse-bpftrace.pl) output as well.
We already have bpftrace tool integration working with pbench. It w…

Currently the approach to viewing multiple processes/threads is to switch between processes as implemented in [#82](https://github.com/jlfwong/speedscope/issues/82), but it would be very nice if inste…

At present we have soak tests that run and give detailed numbers about throughput but with no interior feedback about the behavior of the running vector. This means that users generate their own flame…

If you read Netflix's tech blog, you could easily find extremely useful articles that debugs the performance of the system with flamegraphs

A user complained about slow rendering of flamegraphs, and showed me a video; it was quite slow. Loading the same data into speedscope (https://www.speedscope.app/) was not slow, so the problem was wi…

Is it feasible as it stands, or is it possible to implement a segregation of the perf data into multiple flamegraphs, for example one per unit test or one per benchmark?
This would be useful as a s…

When investigating flamegraph, if one node is too big, the rest is too big to grab. It would be nice if we could have a way to hide big nodes via right+click or using a regex.
See the example below…

https://github.com/risingwavelabs/risingwave/issues/18176 can work in most cases.
But consider when the blocking duration is an hr. There can be no throughput or actor blocking duration metrics at …

Would be cool if a preview of the relevant code can be shown from the flamegraph.
- Could have hovercard that shows function details
- Could link to line in github, or perhaps even open in their c…
