PPP compression is potentially useful at analogue-modem or ISDN speeds, = since even relatively small transfers such as Web pages (which are often = uncompressed from the server) benefit from it. It should be used as an = alternative to modem compression, rather than in conjunction with it; = double-compression tends to be counterproductive. However, it is basically useless for PPPoE, which is typically used on = higher-bandwidth links where latency is a bigger contributor to Web = performance and only larger transfers (which tend to already be = compressed) would benefit. I suspect most PPPoE endpoints in the wild = won=E2=80=99t accept compression negotiation. The default is almost certainly off, and you should keep it that way. - Jonathan Morton
