Hi all,
I will be performing a GitLab upgrade starting in approximately one
hour. While I generally try to do this with more notice and out of
working hours, in this case there is an exploitable GitLab vulnerability
that deserves swift action. Thank you for you patience.
Cheers,

My guess is most of the "noise" is not run time, but the compiled code
changing in hard to predict ways.
https://gitlab.haskell.org/ghc/ghc/-/merge_requests/1776/diffs for
example was a very small PR that took *months* of on-off work to get
passing metrics tests. In the end, binding `is_boot`
I left the wiggle room for things like longer wall time causing more time
events in the IO Manager/RTS which can be a thermal/HW issue.
They're small and indirect though

To be clear: All performance tests that run as part of CI measure
allocations only. No wall clock time.
Those measurements are (mostly) deterministic and reproducible between
compiles of the same worktree and not impacted by thermal issues/hardware
at all.

That really shouldn't be near system noise for a well constructed
performance test. You might be seeing things like thermal issues, etc
though - good benchmarking is a serious subject.
Also we're not talking wall clock tests, we're talking specific metrics.
The machines do tend to be bare metal,
I think the 0.8.1.2 release should be fine for 9.0.2. Could you, Ben,
confirm that?

Hi Oleg, I apologize for the delay in response. I have merged your
Data.List PR and released haskeline-0.8.1.2 containing that change. I will
also look into making releases corresponding to ghc-9.0.*.

Hi Judah,
I'm sending your an email, in case you haven't noticed GitHub notifications.
I have a PR https://github.com/judah/haskeline/pull/153 (now opened for
two months).
It's blocking work on Data.List specialization.
Also Ben have pinged you on https://github.com/judah/haskeline/issues/154
