I just ran a test on the website I just developed for a client, and it is extrememly slow. This is the first time I've used Gantry and Rocket Themes. Here are the results via a couple photos and you can see all the Roksprocket stuff that's slowing the site down.
Check your site with Chrome and in Dev Tools choose network option. You will see that some of your images are huge and this just adds to the page file size. Images that are over 2000px wide and 2.2MB in size and these take time to download. One of your images took 4.24s to download and I am on a fast fibre optic connection.
Optimse your images to the 'Maximum' size you will display them at. This means that slideshow images will be a maximum of 1200px wide and could be saved as jpg with 80% quality to bring them down in size and make them quicker to load. Once the oversize images download they then have to be resized by scripts which is further delay in rendering the page.
Use Chrome Dev Tools to identify other slow areas.
I analyzed your site on gtmetrix.com and concur with David's recommendations for reducing your image sizes and using a caching mechanism such as W3 Total Cache. From experience image sizes are real performance killers.
Appreciate the feedback! Thank you very much-I'll try that! : ) QUESTION--Do images in the worldpress media manager not on a page that's being uploaded still slow it down? For example, I was surprised to see that all pluggins slow down a page upload whether they are used on that page or not.
But here's another page I just started (If you'd like the login info, just say so). I literally just uploaded the rocketlauncher theme MYRIAD for a landing page I intend to build. Check out the results on a test for a site page I haven't even begun to work on! 2.5 seconds already! I thought optimal sites should be no more than 200ms, max 1second.
It feels like this is a gantry framework issue. Your thoughts?
