I only got 97/100 for https://grepular.com/ because:

1.) I have 306 Bytes of inline JavaScript

2.) Minifying https://grepular.com/ more than it already is could save 794 Bytes, ie less than 1% of the page size.

3.) They want me to defer javascript until after page load. It's the last thing in the body anyway...

None of those are valid complaints. Where's my 100% damnit

Earlier quoted context omitted.

I just noticed that your screenshot isn't even of Page Speed. It is of the Audits tab in Chrome Developers Tools.

It is not mine, but gautaml's one, and it use the independent tool of chrome that perform the same test. But when using the webservice it shows different results.

My bad. I wasn't paying attention to the usernames.

Are you sure they perform the same tests though? Why would Google build a Page Speed Chrome extension if the exact same algorithms were already built in? I suspect they are working towards the same goal but are approaching it differently.

I wonder what would happen to my 15% conversion rates if my shopping cart wasn't so crappy... I'm superstitious about switching though because of a fear that it might mess up our organic search traffic.

This suggestion from Google especially looks fun: The following publicly cacheable, compressible resources should have a "Vary: Accept-Encoding" header: * http://www.google.com/buzz/api/button.js However, it's a useful tool. It gives me useful suggestions for improving. Anybody knows a simple tool to minify javascript?

I often use the Closure Compiler at http://closure-compiler.appspot.com/ (online) and http://code.google.com/closure/compiler/ (offline)

Many thanks! I've just found a simple tutorial of how to use it in Python script: http://code.google.com/closure/compiler/docs/api-tutorial1.h...

So, I've written my own script, which minified seven js-files with total size 84.8 KB to one file with size 26.7 KB. Plus gzip and it will be very small.

Thanks again.

There is also UglifyJS https://github.com/mishoo/UglifyJS which is build on Node.

The page Hacker News got an overall Page Speed Score of 86 (out of 100).

Page Speed and YSlow say Hacker News should:

* Enable gzip compression. * Specify img dimensions. * Leverage browser caching: Add Expires headers; Configure entity tags (ETags). * Minify JavaScript

It likely is a different analyzing system but the web appears very much modeled after the audit tab.

I just found it funny that the web gave google.ca 100/100
