However, lower numbers give faster compression at the expense of compression ratio, while higher numbers may give better compression ratios but are likely slower. The level affects the block size, which affects performance, the bigger the block, the faster the compression is. The problem was that higher levels caused bigger blocks: size = min_block_size - 1 + level. the solution is to reverse the above: size = max_block_size + 1 - level.
