Subject: bug#23967: 25.1.50; Slow compilation of ns-win.el
Date: Wed, 13 Jul 2016 14:19:21 +0200 [thread overview]
Message-ID: <m3a8hlhgs6.fsf@gnus.org> (raw)
I've been looking slightly at why "make -j8" isn't as parallel as you'd
expect, and in my tests it's because one single .el compilation job is
weirdly slow.
To test:
If I say "make bootstrap" (to get rid of everything) and then halt the
compilation after it's made bootstrap-emacs
[larsi@stories ~/src/emacs/trunk/lisp]$ time ../src/bootstrap-emacs -batch --no-site-file --no-site-lisp --eval "(setq load-prefer-newer t)" -l bytecomp -f byte-compile-refresh-preloaded -f batch-byte-compile ../lisp/term/ns-win.el
real 0m44.097s
user 0m44.156s
sys 0m0.012s
44 seconds to compile it. From stracing, the thing it says before it
... doesn't say anything for half a minute is:
readlinkat(AT_FDCWD, "/home/larsi/src/emacs/trunk/lisp/international/uni-decomposition.el", 0x7fff42af6240, 1024) = -1 EINVAL (Invalid argument)
So... er... it has something to do with Unicode?
This may not be a bug or anything, but it's perhaps something that
should be looked at to speed up the initial Emacs compilation.
