[geeklog-devel] Reducing the number of HTTP requests

Sun Oct 13 08:07:17 EDT 2013

Just to elaborate on  this a bit.

I did do a test run for combining all css to use the style.css.php (at least
in the Modern Curve theme) so css could be cached by using an etag and speed
things up a bit.

It worked fine except when there are images involved. With the image paths
being hardcoded in the css file and having those paths based on the location
of the original css file the image would never display since the
style.css.php file is located in the themes directory.

I never did see a way around this (unless the original css file is written
to have the style.css.php in a specific location)

       Basically for the plugins  to support Geeklog 1.8.2 and lower.  As of
Geeklog 2.0.0 since we generate the entire page at the end we can take into
account if an autotag gets called and displays something that requires the
css file. With Geeklog 1.8.2 and lower we cannot since the header is one of
the first things generated. That being said I think the latest version of
the polls plugin now requires Geeklog 2.0.0 so that could be switched.

While hunting down some profile spammers, I noticed (not for the first time)
that it does take quite a lot of HTTP requests to load the Geeklog homepage.

Below is a list of what it takes to load and display our homepage. These are
real numbers, grep'ed from the web server log file just now. First column is
a timestamp, followed by the URL and the number of bytes sent.

That's 34 HTTP requests. Note that it takes a full six seconds to send
everything (1 second to render the page, then 5 seconds until the last
resource has been requested). That's not exactly a great response time, to
put it mildly. This will get better on subsequent pages, when the browser
caches things. But 6 seconds is what it takes for a first-time visitor.

(The visitor came from a DSL line and the server wasn't busy at the time)

I see a few obvious things (why are we loading the CSS for polls and captcha
on the front page?) and a few potential fixes (merge JavaScript files; maybe
also some of the images).

Other ideas?

bye, Dirk
