Website SEO optimization is not only about compressing things or combining files or images, It is also changing the type of the data sometimes!
I can create data type images that instead of calling files every time I can use them as page content!
So this image at the top shows our regular usage of images even I use that image type for that post too, since I don’t want to take my time that much on that page since its not really important yet or I don’t have any concern about I will need to rank that page at least not yet. So You will see how that regular image causes no reason wait time! due to server respond! and makes that image to download another 75ms which that makes a total of 181ms wait time that’s crazy!
and that sample unbelievable literally 916ms almost 1 second just to load that sprite image! I just can’t believe webmasters who say sprite images are the best! come on research some even don’t research just read your data! check your guests how many of them use your caches! %60 of visitors don’t get in the cache line. So you got your images as sprites then you will make them load that 1 second every time! that’s so bad developing a strategy.
and look at my precious URI perfect! its only 0.33ms and that’s all. Nothing can beat that time range. Read correctly please. I’m not even saying 1ms it is ONLY 0.33 MILI SECOND!!! so if I have 3 more images then it may be 1ms just! Do you know what that makes;
URI is 3000 times better than sprites & URI is 300 times better than regular images
this is overall my waterfall test all in one page tested by chrome record.
