Re: [xml-dev] Is it time for the binary XML permathread to startup agai

Hi Roger,

1. Compression/decompression times are usually quite fast - time on the 
wire is usually quite slow so even for relatively small documents, 
compression/decompression is worthwhile. In fact this applies across 
lots of uses, not just XML. Even Gbit networks benefit from this.

2. Not all XML is sent from a web server so that point is really not 
relevant.

Regards
Rick
