The ideal library would have high compression speed and low compression ratio. We can see that `brotli` covers the widest range, giving us the option to have the slowest compression speed in exchange for the lowest compression ratio, but also the second-fastest speed with the highest ratio. It is also immediately noticeable that `zlib` consistently gives compression ratios that are higher than desirable for the speed being compressed. Both `xz` and `lzlib` perform very similarly, where they do not offer the same range of options that `brotli` and `zstd` do, and they only operate in the slower and lower compression ratio end of the spectrum, but they are an improvement over `brotli` and `zstd` within that range.

In the end, to compare each library with the most similar compression speed to `zlib` at compression level 1 we see:
