OK, here are some more issues.

I am running the my main build in ANT 1.6 vs 1.5
and I am getting very disapointing numbers:

On ANT1.5 a full build takes 9m23s

On ANT1.6b3 the same build takes 14m12s (!!!!!)

On ANT1.6b3 a modified version of the build takes 11m3s

This is after modifying the build for 1.6 to use
<macrodef> in a couple of obvious places instead of <antcall>.

This is on a build file with over 2500 lines and with
numerous <antcall> and <foreach> loops.

I can extrapolate from this two things:

a) <macrodef> really helps in 1.6.

b) I will have to convert a lot of the code to just
get the performance I had before. If I move the
rest of the developers to 1.6 as is, they will kill me.
They already complain the build takes too long.

Any insight on what we should look into?
We cannot ship 1.6 with such issues, I do not think.

Jose Alberto
