Comment(by chhenning@…):

 John, thanks for all of your work. I did update my boost trunk and rerun
 my test. Both boost and ATT are pretty much on par with each other. Att
 still being slightly a faster.

 Test is to compare boost's gamma quantile function vs. Att's cdfgam

 Boost - 19.968sec
 Att - 18.547sec

 This is very good! I have used VS2005 producing 64bit code.

 Can you summaries how you almost doubled the boost performance?

 Thanks again for your great work. I can now propose to use boost::math at
 my work.
