Description Gary Gregory CLA 2003-11-18 18:47:46 EST 
Ant support is getting there! Pretty cool! BUT...

I have a build.xml which is 1007 lines and it takes b/w 4 and 5 seconds to save
to disk. I would be nice to improve performance in this area.

FWIW, my machine specs are:

Moving to Platform/Ant.

We will be doing more performance passes in M9 but this should be greately 
improved from when this bug was filed.
Comment 4 Darin Swanson CLA 2004-05-12 15:25:22 EDT 
Gary are you still seeing problems in this area?
Comment 5 Gary Gregory CLA 2004-05-12 22:02:58 EDT 
Using version 3.0.m8 seems much faster, 1 or 2 seconds, definitevely acceptable.
The build file is ~now 2700 lines. Thank you.
Comment 6 Darin Swanson CLA 2004-05-13 00:25:48 EDT 
That is one biiiiiggg build file!  Glad the speed is working for you
Going to mark this as worksforme as cannot reproduce any significant problems 
either (but my test case is only 1700 lines :-) )
