Project Description

I find myself often rerunning the same preprocessing tasks on perf captures, like one-liner scripts to merge/split per-cpu data, time-slice them, filter for specific events and finally plot charts (flamegraphs, heat map, ...). Each time one of these tools run perf-script, just loading 30s worth of events from a large machine can consume precious seconds in my modern laptop. The idea is to provide an interactive tool a la GDB and drgn where we can load the events once and manipulate them interactively to generate different visualizations.
