print is slow under mod_perl

[Alvar Freude <al...@merz-akademie.de>]

Hi,

on my machine each type of print / output under mod_perl to the browser
is VERY slow!


checked with embperl or plain mod_perl: if the text length is long, it
takes a lot of time, e.g. about 4 seconds for an 200 KByte text, checked
from localhost!

the hole calculating time before output is about 0.25 seconds.


CGI Perl is as fast as expected.


has anybody an idea?



I use Apache 1.3.12 and mod_perl 1.23



Ciao

Hi,

yes, static text and CGI: no problem, as fast as expected. Only
everything running under mod_perl is slow. very strange ...

no, i checked it with apache bench!


So, i hope with the next update it is away; or with the next full system
update -- i have to reinstall the hole machine and guess it works fine
after it is new, if no other have the same problem it should be a
problem of my installation.

Do you see the same problem with static text ?

Could it be a difference between MSIE and Netscape, like Eddie described in
his post ?

no, that has nothing to do with embperl, it's the same with plain
mod_perl, so I guess it's a mod_perl problem:


Plain mod_perl:

	$r->header_out('Content-Length', length($$textref));
	$r->header_out('Connection', 'close');	
	$r->send_http_header;
	
	$r->print($$textref) unless $r->header_only;
	$r->rflush();



hmmm!

Looks like you have an Embperl 1.3 beta version. In some of them was a bug
in calculating the content_length, so the browser waits until a time out
before he displays your text. Upgrade to 1.3.0 should solve this problem
