But change d180m by :d256m and it takes longer to compress, but compresses a little more.

My question is, how do I use my cpu 100% because in the image it is only seen that it uses 50% when compressing

[External compressor:rep,mm,delta,exe,exe2,4x4,lzma]
header = 0
packcmd = FAZip64 -i0 compress:{compressor}{ption} <stdin> <stdout>
unpackcmd = FAZip64 -i0 decompress:{compressor}{ption} <stdin> <stdout>

4x4:lzma: a1: mfbt4: d180m: fb273: mc10000: lc8
But the more RAM
