Hi,
Another (sort of) related question: I've got the bandwidth
measurements for different algorthms using netperf. I was
really surprised that IPComp did so bad. Any ideas?
TCP UDP(Mbps) Ping(ms) Key(bits)
-----------------------------------------------------
Raw IP 79.56 94.59/87.98 0.213
des-cbc 40.60 46.51/36.88 0.389 64
3des-cbc 19.52 22.18/19.37 0.460 192
simple 78.53 93.44/86.93 0.293 64
hmac-md5 72.86 93.86/44.57 0.398 128
blowfish-cbc 23.24 55.18/42.12 1.063 64
rc5-cbc 46.22 65.67/45.29 0.383 64
hmac-sha1 45.30 64.04/49.69 0.440 160
IPComp-deflate 24.05 27.11/27.10 0.242
Setup: 2 identical freebsd 4.2 release boxes (PIII 733MHz,
256MB RDRAM) connected through Ethernet switch.
Thanks,
yushun.
