Brotli compression module and PageSpeed Insights

[Passepartout Spa]

Hi,

I’ve installed Brotli compression module on web server with Windows Server 2012 R2 and IIS 8.5.

In IIS 8.5, my site is a ASP.NET MVC application, and when I do test from PageSpeed Insights (https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fwww.101copia.passweb.it%2F&tab=desktop), my website is faster than before, but screenshot of  PageSpeed Insights is incomplete, why?

This is Otto's answer:

"Hi,
 
We don't know. The PSI discussion list [1] would probably be a better place to ask.

Kind regards,

How can i check if PSI working correctly?

I suspect the problem is you're timing out so only the background image is displayed.

Reduce server response time

In our test, your server responded in 8.3 seconds.

Hello!

In our test, your server responded in 8.3 seconds.

Which is way too much - good sites load most pages in far less than a second.

Cheers, Thomas

Something isn't right on the setup.

Http works great and https (which brotli uses) just hangs.

Time to check your setup. (All browsers requires SSL to use brotli.)
