9 okay, its bad form to reply to your own posts...but i did some very crappy
10 benchmarking (cat /proc/uptime >/tmp/boottime in /etc/conf.d/local.start),
11 and booted each set of rc-scripts 10 times.
12
13 results inconclusive...sometimes LC_ALL=C booted faster, sometimes without
14 did. and with either enabled, boot times would fluctuate between 17 and
15 15.9 seconds for a full boot, no clear win with LC_ALL=C enabled.
16
17 i did some more research, and it seems this hack is necessary on Red Hat
18 because they set LANG to a UTF locale on bootup. something which Gentoo
19 doesn't do. at least, a grep for LANG in /etc turned up nothing.
20
21 unless grep/awk default to a UTF locale in the absence of LANG,
22 it seems Gentoo is already as fast as it can be in this regard.
23
24 i think a note should be made if Gentoo at some point in the
25 is going to set LANG, though.
26
27 sorry about blowing smoke...i think i just witnessed one of faster bootups
28 after changing to LC_ALL=C. this will teach me...
