I read somewhere that if the website could parallelize the connections , the website will load much faster.
Is this true ?
Let's say I want to use timthumb script to generate thumbnails for my WordPress site. I'm using a theme with a lot of thumbnails on the front page and sidebar. (30 on the main content and 20 on the sidebar). This means a lot of request for the timthumb.php and for the server.
Now comes the questions:
1. If I move all the uploaded images to a subdomain (sd1) and the timthumb script to another (sd2), does this make my site to load much faster?
2. But if I set one timthumb script to generate a part of my thumbs, from the main content to subdomain sd1, and another timthumb script from subdomain sd2 to generate the thumbs from sidebar ?
I suppose this means to parallelize the connections for a website.
Is this a way to improve the website performance ?
