improve unsafe Decompression Performance ~4% #114

Closed PSeitz closed 1 year ago

PSeitz commented 1 year ago

This is another attempt to replace the aggressive compiler after the failed attempt #69 (wrote out of bounds in some cases)

The unrolling is avoided by manually unrolling less aggressive. Decompression performance is slightly improved by ca 4%, except the smallest test case.
