Subject: bug#24720: Performance impact of -no-pie
Date: Mon, 17 Oct 2016 13:18:51 -0700 [thread overview]
Message-ID: <60845a3c-9167-faa1-2875-962e7025cc1f@cs.ucla.edu> (raw)
(The rest of this message is copied from Alex's email archived at
<http://lists.gnu.org/archive/html/emacs-devel/2016-10/msg00451.html>.)
After being forced to add -no-pie to my CFLAGS in order to build Emacs with a recent GCC, my startup time for my whole config (with -nw) has increased from ~1 second to ~2 seconds.
The startup time for `emacs -Q -nw` went up from about 0.07s to 0.14s; again it's about twice as slow.
The -Q time doesn't worry me, but the extra second for my main configuration isn't pleasant.
Is such a performance impact expected? If so, is there a plan to regain the old speed?
