const BufferSize = 1024 * 1024

const Workers = 8
For best I/O throughput we want to have enough in-flight requests, regardless of number of cores. For best decompression we want to use one worker per core, but too many workers is less effective. The default value gives good results with lima default Ubuntu image.
