By read many times I mean a file that is opened many times. For instance, the kernel and libraries every time you boot.
From my understanding (but please correct me if I am wrong), LZ4 will decompress them significantly faster than ZSTD even if the latter compresses more.
In other words, the decompression speed is measured on the decompressed data, right?
Yes, speeds are measured relative to the uncompressed data. ZSTD outputs around 600-2000MiB/s/core (in all the higher levels), depending on how fast your processor is.
