I am seeing similar results for CDS [1]: Gzipped PCAP CDS Factor client 108136 45944 0,4248 zonalizer 12468329 2485620 0,1993 large ditl 327227203 117569598 0,3592 small ditl 539323 253402 0,4698 Xzipped PCAP CDS Factor client 76248 36308 0,4761 zonalizer 7894356 1695920 0,2148 large ditl 267031412 86747604 0,3248 small ditl 442260 206596 0,4671 > - It requires around an order of magnitude less CPU to compress the C-DNS > file.
