google pagespeed / gtmetrix – how to improve results

May 28, 2015Metrics, WordpresspagespeedPF

Check if we have enabled mod_headers.c and mod_expires.c

First we need to check if we have enabled mod_headers.c and mod_expires.c.

sudo apache2 -l

If we don’t have it, we need to enable then

sudo a2enmod headers

Then we need to restart apache

sudo apache2 restart

Defer parsing of JavaScript

To solve this issue I’v installed Asynchronous Javascript WordPress plugin.
It went from a score of F (19) to B (85).

I strongly recommend to install Google PageSpeed module.

ThemeForest – the end price

May 22, 2015Sh*tsthemeforest, vatPF

From a listed 16USD we end paying 22.14USD for it.
A handling fee – they need to pick the theme from a warehouse, package it, send it… 2USD.
And the the VAT…

Unused CSS – clean up css stylesheets

May 16, 2015Sh*tscss, performancePF

Well,

Most of *tutorials* about speed optimization that I’v seen talk about minify css, combine them etc… today I’v faced myself (lol) in to a problem… I’m using Flat UI – Free Bootstrap Framework and Theme on a very simple html page. That page will be delivered in a zip file and I just want the HTML itself… So, I want to put the CSS in the HTML but I don’t want the unused stylesheets on it…

So I’v installed CSS remove and combine from Steve McArthur.

Some graphs taken from https://unused-css.com/ about the used/not used CSS selectors/stylesheed.

bootstrap.min.css

27% of the CSS selectors are used
The cleaned CSS file size is 61% smaller

demo.css

Css usage after cleaning 7% of the CSS selectors are used
The cleaned CSS file size is 85% smaller
