Test results - help needed!

Hi I’m relatively new to web development and need help with my test results.

Please could you advise where to start?

Look at your content breakdown: http://www.webpagetest.org/breakdown.php?test=150318_XP_T48&run=1&cached=0

image 122
js 32
css 15

122 images! On one page! Do you really need that many images immediately on page load? Maybe load a couple of images at first and load the rest as needed? Those 122 images add up to 4.6 MB!

32 JavaScript files! You don’t need one JS file for each jQuery plugin; you can consolidate these into a single file. Or better yet, remove the ones you don’t need.

15 CSS files! See above.

Start with that.
