How good is this? - shivaganesh - 09-29-2014 05:44 PM

Hi,

Please review my site and let me know how 'good' or 'bad' my results are?

Thanks a ton!

Looking at the waterfall, it looks like the page starts to load and then around request 40 it gets thrown away and re-loaded (probably by some javascript code on the page): http://www.webpagetest.org/result/140929_7P_D28/1/details/

That's a REALLY bad idea and added 5 seconds to the load time of the page.

It also looks like you have some enormous png images that should be jpeg's (200-500KB, the bee hive, crayons and a bunch of the others): http://www.webpagetest.org/pageimages.php?test=140929_7P_D28&run=1&cached=0

Thanks!

I connected to Cloudflare now I can see some difference in the score - http://www.webpagetest.org/result/141008_ZG_HBZ/

If I change the PNG to JPG, the resolution is compromised... Thanks for your suggestion!

Have you actually tried saving the images as high-quality JPEGs? The resolution doesn't change and without running a pixel diff I'd be VERY surprised if you could even find differences if you were looking for them.

Using most image tools, a quality level of 85 for JPEG is usually visually indistinguishable from the original PNG but a much smaller file size. If you're using Photoshop then the scale is different but save-for-web at a quality of 60 is usually a safe bet.

For example, the beehive picture is a 435KB png:
[attachment=435]

And as a 106KB JPEG:
[attachment=436]

All of the other large PNG's can get equivalent savings without even spending time doing much tuning (you could get even smaller by adjusting compression settings for each of them).
