Yeah, we don't have scripts of this kind to compare the perf results,
but I think we need some.
At present, I am running perf tests continuously, and feed the result
to codespeed, in which the performance is shown as some diagrams. I
open them in web browser every day, to see if there are any perf
regressions. codespeed doesn't meet our needs perfectly, so I am
only running it in house and don't propose using it for GDB.
Performance data collection has been done, but perf data record
and comparison is still missing. I've had some thoughts, but
incomplete. I'll assemble them for a post to see how much we
can do here.
