--- Begin Message ---Package: emacs Version: 1:29.1+1-2 Severity: wishlist native-comp-async-jobs-number is a variable defined in ‘comp.el’. Its value is 0 Default number of subprocesses used for async native compilation. Value of zero means to use half the number of the CPU’s execution units, or one if there’s just one execution unit. I think the upstream default is too aggressive, and we should set it to a smaller number to reduce the "fork bomb" like behaviour of spawning NUM_PHYSICAL_CORES worker processes for each user created emacs process. This particularly manifests itself if the user is running more than one emacs process. As an example, prior to patching the notmuch test suite, I got 200 native compilation processes on my desktop. Upstream may be correct that "one emacs process per machine" is the most common scenario, but the bad outcome of having the limit too small seems better than the bad outcome of having it too high. People do use emacs in lots of other scenarios (e.g. servers and automated processes), and expecting them all to customize their emacs to avoid a performance / UX regression seems unkind. AFAICT since the native compilation is asynchronous, there is no obvious pause by queuing the compilation jobs. -- System Information: Debian Release: trixie/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 6.4.0-2-amd64 (SMP w/12 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages emacs depends on: ii emacs-gtk 1:29.1+1-2 emacs recommends no packages. emacs suggests no packages. -- no debconf information
