[Scons-users] Speeding up large C/CPP projects...

[Dirk Bächle]

Hi there,

I added a new Tool to the index at:

   http://www.scons.org/wiki/ToolsIndex

. Its name is "fastcpp" and it aims at speeding up large C/CPP projects. 
This is achieved by taking a few shortcuts, which further means that the 
Tool may break your builds in a very bad way (or, even worse, in a very 
subtle way ;) ).
So try it out, if you're an adventurous person...but please read the 
full description of changes in its README.rst file before.

Finally, here are a few figures for two benchmarks ( as used at 
http://www.scons.org/wiki/WhySconsIsNotSlow ) :

   questfperf (5000 CPP files):
   ============================

                   clean build     update    implicit_update
     default 17:11.42      0:24.45 0:17.07
     with fastcpp    17:00.76      0:19.97       0:16.20

   sconsbld (8000 C files):
   ========================

                   clean build     update    implicit_update
     default         7:04.22       0:34.96 0:26.19
     with fastcpp    6:44.56       0:27.50       0:24.87


Best regards,

Dirk
