Opensource PDF generator : wkhtmltopdf

wkhtmltopdf and wkhtmltoimage are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the Qt WebKit rendering engine. These run entirely "headless" and do not require a display or display service.

There is also a C library, if you're into that kind of thing.

I am writhing this post just to keep record of what actually worked for me - the command I mean.

PATH_TO_wkhtmltopdf\bin\wkhtmltopdf --header-spacing 14 -T 22mm --header-html header.html cover cover.html toc --xsl-style-sheet toc-default.xsl article.html article_to_publish.pdf 

The command above prints a page as pdf with cover page, table of contents and header The TOC layout used is generated using a command as bellow:

PATH_TO_wkhtmltopdf\bin\wkhtmltopdf --dump-default-toc-xsl >> toc-default.xsl

Full document can be found here, which definitely I din find quite qood. 

Testing the performance of a web application

Currently, I am working with a web application and one of the main duty is to improve the performance of the application. I am trying to reduce the page refresh time first. Here I m going to note down all the tools and techniques I am utilizing.
To identify exactly what is bottle-necking I used the following tools:
FireBug
IE Developer tools
Yslow
Pagespeed
Fiddler
I needed to compress/minify my css and js files. I got some tools that are of high rank. But finally I wrote my own tool to perform the same :

Some of the clients has very slow internet connection. Therefore I needed to test the site using low speed internet  To accomplish that following tools were very useful.
Sloppy
