Asset compression with -9 #21

Closed thekid closed 3 years ago

Use a compression level of 9 when compressing:

Reduce compressed file size
Speed up decompression time (!)

In all cases the file decompressed faster if it had been compressed with a higher compression level.

Savings in my case:

File	Uncompressed	Before	After	Delta
vendor.7b1f7cb.js	795.95 kB	231.68 kB	229.87 kB	1.81 kB
vendor.4d33b13.css	1330.04 kB	158.02 kB	154.79 kB	3.23 kB

We get about 3 kB of reduction, which isn't much, but it comes at virtually no cost when bundling, a slightly better runtime performance and if you multiply that times the amount of downloads, it might be noticeable:

We could potentially get even more savings by using https://github.com/kjdev/php-ext-brotli
