I just tried turning this on. Again, it makes no difference to the speed,
but I can see that some of the javascript files are being cached; at
least, they are not being asked for every time.
The main ticket pages are served with Pragma:nocache and
Cache-control:no-cache. Also Connection:close which I believe thwarts
pipelining. (according to the "live HTTP headers" plugin)
(for the benefit of others, these tweaks are under the
pseudo-location "about:config" in Firefox3, after a dire warning about
"are you sure you know what you are doing?")

Chaim Rieger asks "anything in Apache logs?"
Nothing to my (rt3) untrained eye.
I see my ticket view request getting answered e.g.
GET /Ticket/Display.html?id=2085 HTTP/1.1" 200 75857
In the error logs, I see some errors earlier in the day, not associated
with my simple requests, e.g.
FastCGI: server "/opt/rt3/bin/mason_handler.fcgi" stderr: \teval {...}
called at /usr/lib/perl5/vendor_perl/5.8.8/HTML/Mason/Request.pm line 467
I had not seen these prior to adding some tuning to
/etc/httpd/conf.d/rt3.conf, viz.
PerlSetVar MasonStaticSource true
PerlSetVar MasonBufferPreallocateSize 4096
PerlSetVar MasonPreloads '/Elements/*'
the original contents of rt3.conf are
Alias /rt3 "/usr/share/rt3/html"
PerlRequire /usr/sbin/webmux.pl
<Directory "/usr/share/rt3/html">
AllowOverride All
Options ExecCGI FollowSymLinks
RewriteEngine On
RedirectMatch permanent (.*)/$ $1/index.html
AddDefaultCharset UTF-8
SetHandler perl-script
PerlHandler RT::Mason
</Directory>
I did not do the install myself, but I believe everything is correct. RT3
is working, I just think it's slow.
What response time are others seeing on the Web interface ?
