so the best scaling is to use 4x4:lzma:a1:mfbt4:d64m:fb273:mc10000:lc8 it work ( i mean that it use the CPU 100% on all setting like pentium-i3-i5-i7)

I can't find any written document but judging from this

else switch (*param) { // Ïàðàìåòðû, ñîäåðæàùèå çíà÷åíèÿ
case 'b': p->BlockSize = parseMem (param+1, &error); continue;
case 't': p->NumThreads = parseInt (param+1, &error); continue;
case 'i': p->NumExtraBuffers = parseInt (param+1, &error); continue;
case 'r': p->MinOrder0Percents= parseDouble (param+1, &error); continue;
}

i think

4x4:t%NUMBER_OF_PROCESSORS%:lzma:a1:mfbt4:d64m:fb2 73:mc10000:lc8

is betther idea

remember there is no constraint that you need the same number of cores to compress and decompress, so by using external compressor i.e. fazip you can fully control the CPU usage in both compression and decompression

decompression it use only 128mb + srep you can limit the memory

still, it will write the required memory on hard drive making the process a little bit slower
