Web browers are bogus. I used the 'show ipcp' command from within an
interactive ppp(8) session (I usually run one on a spare VT). Along with
'show ccp' this tells you what sort of compression is running on both
sides, the overall, current and peak transfer rates.

I was never too pushed to test this, since I don't use PPP w/computer over
anything but modems, and modems are very high latency. Anything over ISDN
or other mediums I do with dedicated routers.
