Re: [gentoo-user] Slow application start, LC_CTYPE and XCreateFontSet

[Vladimir G. Ivanovic]

Initially I had similar behavior as you, except that en_US.UTF-8 was faster and others slower (my laptop is a 1.8 GHz AMD64).

Maybe you should post your question on some X-related mailing list.

But, after repeated invocations of 'time xterm ...' all versions settled down to the same value: ~0.25 seconds.

Hello,


Setting locale to anything else seems to solve it (even en_US)

$ time LC_ALL=en_US.UTF-8 xterm -e echo
real    0m2.422s
user    0m0.010s
sys     0m0.012s

$ time LC_ALL=cs_CZ.UTF-8 xterm -e echo

real    0m0.065s
user    0m0.048s
sys     0m0.010s


Specificaly, it seems to be related to LC_CTYPE setting.

strace shows lots output similar to:
poll([{fd=3, events=POLLIN, revents=POLLIN}], 1, -1) = 1





Any ideas how can I solve it?




I generated all possible locales with locale-gen -A
I use fluxbox-1.0.0-r2

Any help is greatly appreciated

I've installed new laptop few weeks ago and everything is running fine except for all (most?) X applications taking few seconds to start. I've tracked the problem down with ltrace to "XCreateFontSet()" call that blocks for more than 2 seconds. Searching on google lead me some forums about problem with this call and UTF-8 encodings. Further tests showed that the problem is related only to having locale set to en_US.UTF-8. That's probably the reason I never saw it before, I usually have some non-english locale on my system. (czech/japanese/russian, none of them affected) read(3, "\1\0\212\0\0\0\0\0\0\0\351\0\0\0\0\0\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", 32) = 32 writev(3, [{"1\1\t\0\1\0\32\0", 8}, {"*-*-*-*-*-*-KSC5601.1987-0", 26}, {"\0\0", 2}], 3) = 36 read(3, 0x7fff831995a0, 32) = -1 EAGAIN (Resource temporarily unavailable) I tried to generate al locales with 'locale-gen -A' and to install some other fonts (to have the same font set as on other machine where it works fine) and nothing helped at all. Does it mean that I'm missing some fonts? Or something else? I'm running out of ideas what to try... my X server is xorg-server-1.3.0.0-r6 compiled with USE: dri input_devices_joystick input_devices_keyboard input_devices_mouse input_devices_synaptics ipv6 nptl sdl video_cards_nv video_cards_nvidia video_cards_vesa xorg xprint
