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
