BB2 performance.

Hi all,

First, let me say that design of boost build looks very good, the features 
available are an almost exact match for what I would say an ideal system for 
describing building of source code. However, we've been conducting 
performance analysis on boost build2 M10 inhouse and found that both the 
build times and dependency checking seems to be considerably slower than 
just plain vanilla jam, in fact it's on par or worse than scons, which seems 
to be one of the slowest system out there. For a full rebuild it's around 
twice as slow as vanilla jam (can this be due to the constant calling of 
vcvars32.bat?) and for a dependency check (call build again without anything 
changed) 18 (!) times slower than vanilla jam. The question is, can I 
somehow in a few easy steps tweak something or patch something so that the 
whole system runs a little bit faster? Any tips?

Regards,
Jim Tilander
