Re: xemacs 20.3 slow load
Hi-
Many thanks to those who have commented thus far on the xemacs slow load post.
Being relatively new to Linux, i am still slogging thru the process of
analyzing why
the load takes so long on my machine.
In particular, i have just run an strace on the program as it loads, and it
gives me about
280k worth of text file on the system calls, many of which are mysterious
to a newbie
like me.
If find particularly interesting any lines in the file where a timeout
occurs. I have attached
a snippet below, which is repeated many times in the load process. Could
anyone shed
light on just what is happening here?
I will continue to try and understand analyze the file in the meantime.
Many thanks again
Jerry

Re: xemacs 20.3 slow load (follow up)
Hi - I just started up xemacs while connected to my ISP and it came up in under 3 seconds! The timeouts (there are 225 of them) i reported previously are apparently related to unsuccessful attempts to connect to my ISP while i am offline! Is there a way to instruct xemacs not to try and connect the socket? Progress! Thanks again Jerry -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word unsubscribe to [EMAIL PROTECTED] .

Re: xemacs 20.3 slow load
That doesn't sound right. You should have something like: 127.0.0.1 zeropoint.your.domain zeropoint 127.0.0.1 localhost (Also try flipping those lines around.) Also, what does hostname and hostname -f report? Gerald Wann [EMAIL PROTECTED] writes: I am experimenting with xemacs 20.3 on debian linux 2.0.29 machine w/ AMD K6 200MHz / 32M RAM.

With the help of the strace(1) utility I found the following interesting behaviour of XEmacs19. The XEmacs I am using is version 19.16-1 which comes with the unstable distribution. When XEmacs starts up it creates a UNIX domain socket and tries to connect it to /tmp/.sockets/audio0. If this special file does not exist (ENOENT is returned) it does nanosleep(2) five times and sleeps about 1 second each time. Only after nanosleeping it will continue loading. If a plain file named /tmp/.sockets/audio0 is created XEmacs gets ECONNREFUSED as return value and goes on without nanosleeping or retrying. This speeds up the startup time for about five seconds on my machine. /usr/bin/time reports the time going from about 8.7 to 3.7 seconds.
