How to use large window sizes?

[bdnbje]

I built brotli using the latest sources, but the window size is limited to 16mb. How do I set it to larger window sizes like 512mb?

Hello.

Currently we are testing "Large Window Brotli" extension that will allow up to 1GiB window.
Hopefully, it will be published this week.

can I make any trade-offs to improve ratio?

"Large Window Brotli" is landed.

We constantly work to make quality=11 denser. You could play with some internal constants, but, most likely they won't provide big improvement.

To give a more specific advice, I have to know the use case...
