I have 1.92 s page load time but my blog is really clean.I try to control my page load time but can you tell me how much seconds is the limit to be good optimized.Thank you
If that is the total load time from request to everything downloaded by your browser, yes, that is a good time. There is no rule on the number of seconds a page should take a load. Generally, the faster the better. But pages with multiple file requests and images and stuff will take longer. I would say 3 - 5 seconds is acceptable and any higher than that would be unacceptable from click to render.
I see a lot of major websites loading much longer, some advertisements or other third party scripts sometimes take more than 10 seconds to load (I'm on 16mbps connection). 1.9 seconds is a good time for all resources to be loaded. I am also an optimization geek and try my best to reduce the file sizes and remove unnecessary content/resources where possible. You can optimize your JS, CSS files and reduce the HTML by removing comments (if applicable), empty spaces, new lines etc. Images can be optimized a lot. I use two free programs for PNG and JPG optimizations and highly recommend them: http://pnggauntlet.com/ https://saerasoft.com/caesium/ You can also check your resource loading times at http://tools.pingdom.com/fpt/ and see if you can optimize or get rid of any of them.
