Fine Tuning Http2

RE: Fine Tuning Http2
Hi Brian,

I think you've come across what some others who are implementing HTTP/2 have run into with splitting combined script files.

The issues stem from how the compression algorithm works and processing of multiple files. Compressing larger files is typically more efficient. Smaller files don't compress as much. And having more files to process could impact server performance.

These are probably a couple of the things you're running into.

A good example of this issue was experienced by Khan Academy, when they moved to HTTP/2 -- http://engineering.khanacademy.org/posts...-http2.htm

You have to look at your own JS and CSS files, but depending on how many you have, you may want to keep them combined.

Also, comparing page speed with HTTP vs HTTPS may be comparing apples to oranges, if HTTP is running with HTTP/1.1 and HTTPS is running with HTTP/2. Overall use of your site should benefit with the other HTTP/2 features, like multiplexing, that HTTP/1.1 does not have. If that's not the case, let me know.

Hope that helps.
