Perfetto

Notes on using perfetto

downloading and use trace_processor to easily export traces to SQL tables
- trace_processor <trace> -e db.sql dumps the table trivially
- this makes it much easier to do analysis across multiple traces
the slices table is my favorite, can also query from within perfetto
- they also have sql macros in the UI
highlighting a region allows generating flamegraphs easily (can be slow)
shortcuts like Ctrl-A work for selecting parts of the trace
counters are pretty cool to highlight numerical values
