Precomp -brute0
reflate can not handle more than 4GB of files, use the precomp in brute mode result is the same but the unpacking faster! But do not forget that the usual hdd packing becomes duty!
ps do not spoil your hard disk by using reflate in their repack! SSD can withstand a number of small files, no hdd after recording 2-3 times drive to the dump!

Reflate is the fastest deflate software you can find....The only big differece b/w reflate & precomp is that precomp keeps compiling all processed deflate streams in one .pcf file whereas reflate keeps it separate...

There are many ways with which you can even fast up your decompression in reflate. For example use multiple threads for hif to raw conversion......

As for size limit, I never experienced a single error on that ...... Also you can change solid block size to overcome that problem......

What`s the best command line for using precomp 0.43 in brute mode?

precomp -brute0 -cn -t+zgn -d0

Or if you wanna avoid PNG multi parsing (brute mode will catch the streams inside PNGs, but act like reflate for multis), use this:

precomp -brute0 -cn -t+zg -d0

Thanks. But why these parameters?

-cn -t+zgn -d0
