 This is some basic observation's I've made about this library's performance when compared to `unsquashfs`. Unless otherwise stated, most observations were made when extracting my test archive (which is fairly small and uses zstd compression) and with `--release=fast`.
 
-* Under ideal circumstances, my library is ~70% slower (.11s vs .18s)
-* Mutli-threading on small archives significantly increases extraction times (when using C libraries) (.18s vs .57s). This should theoretically reverse on larger archives with many inodes, but I haven't tested that yet.
-* Using Zig libraries *significantly* increases decompression time by ~600% under ideal circumstances.
+* Under ideal circumstances, my library is ~60% slower (.12s vs .19s).
+* Using Zig decompression libraries *significantly* increases decompression time by ~600%. Under ideal circumstances.
+* Performance improvements/regressions will be common. I'm still learning Zig.
