+# Benchmarking scripts for Lix
+
+These are very much WIP, and have a few clumsy assumptions that we would
+somewhat rather be fixed, but we have committed them to let others be able to
+do benchmarking in the mean time.
+
+## Benchmarking procedure
+
+Build some Lixes you want to compare, by whichever means you wish.
+
+Get a computer that is not busy and *strongly preferably* is bare-metal or at
+least not a cloud VM (e.g. go make coffee when running benchmarks).
+
+From the root of a Lix checkout, run `./bench/bench.sh resultlink-one
+resultlink-two`, where `resultlink-one` and `resultlink-two` are the result
+links from the builds you want to test (they can be any directory with bin/nix
+in it, however).
+
+To get the summary again, run `./bench/summarize.jq bench/bench-*.json`.
+
+## Example results
+
+(vim tip: `:r !bench/summarize.jq bench/bench-*.json` to dump it directly into
+your editor)

+Lix now enables build options such as trapping on signed overflow and enabling

+present themselves as Lix processes aborting, potentially without an error
+message.
+
+If Lix processes abort on your machine, this is a bug. Please file a bug,
+ideally with the core dump (or information from it).
+
+On Linux, run `coredumpctl list`, find the crashed process's PID at
+the bottom of the list, then run `coredumpctl info THE-PID`. You can then paste
+the output into a bug report.
+
+On macOS, open the Console app from Applications/Utilities, select Crash
+Reports, select the crash report in question. Right click on it, select Open In
+Finder, then include that file in your bug report. [See the Apple
+documentation][apple-crashreport] for more details.

+synopsis: using `nix profile` on `/nix/var/nix/profiles/default` no longer breaks `nix upgrade-nix`
+cls: 952
+---
+
+On non-NixOS, Nix is conventionally installed into a `nix-env` style profile at /nix/var/nix/profiles/default.
+Like any `nix-env` profile, using `nix profile` on it automatically migrates it to a `nix profile` style profile, which is incompatible with `nix-env`.
+`nix upgrade-nix` previously relied solely on `nix-env` to do the upgrade, but now will work fine with either kind of profile.
