Description shelmberger 2004-04-15 14:15:26 UTC 
The execution time for my webapp  project build
(for complete cycle from cleaned state) is nearly
tripled in 3.6.

The complete build after clean takes about 13
seconds with :

- Ant from Netbeans 3.5.1
- Ant 1.5.4 from gnome-terminal
- Ant 1.6.1 from gnome-terminal

Ant Execution from Netbeans 3.6 takes up to 1
minute. (the log level makes no difference. "only
errors" is as fast as "verbose")

The performance loss seems to be spread across the
whole execution (There is no single task which is
slower).

I am unaware of anything which would have caused a significant change
in performance w.r.t. running Ant in NB 3.6. Will close soon unless
there are detailed steps to reproduce from scratch, i.e. a benchmark
of some kind.
Comment 2 Petr Nejedly 2004-06-17 15:58:10 UTC 
Haven't reproduced it either.
For me, the execution takes the same amount of time after long coding
(with ant cooled down -- released classes) as from console,
and if I try to measure two executions in a row (to keep ant
preheated), the one invoked from NB is always faster.
