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’t accept compression negotiation.

The default is almost certainly off, and you should keep it that way.
