Subject: bug#27780: guix environment to build guile from git required excessive CPU time
Date: Thu, 20 Jul 2017 23:02:47 -0400 [thread overview]
Message-ID: <87pocucx0o.fsf@netris.org> (raw)
I just ran the following command on my Thinkpad X200 running GuixSD:
./pre-inst-env guix environment guile --ad-hoc autoconf automake libtool flex gettext
Using the guix client from a git checkout at v0.13.0-1496-gcfd6a3b1e,
and using guix-daemon from guix-0.13.0-3.b547349.
This command took approximately 20 minutes of CPU time before
downloading anything except possibly some NARINFOs. During this initial
20 minutes of CPU-bound activity, the only output was 4 occurrences of
the following message:
substitute: updating list of substitutes from 'https://mirror.hydra.gnu.org'... 100.0%
The CPU time was roughly evenly split between the following two
processes:
--8<---------------cut here---------------start------------->8---
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND

--8<---------------cut here---------------end--------------->8---
Immediately before this, I had run the same command but without the
final "gettext" argument, and it ran quite quickly.
I've run a similar command in the last couple of weeks, with the
"gettext" argument, and as I recall it ran reasonably quickly as well.
