Subject RE: Performance difference between 1.6.1 and 1.6.4 (in eclipse)

well this wasn't a problem until 1.6.3. ;-)

No this is no problem.

Some descriptions of the script:
There is one include statement including a script that merely defines several properties
and has no targets. Additionally there are several properties defined in the script.
Each get*Artifacts target defines additional properties based on the included properties,
tries
to create one or more directories and calls the presetdef "see.get" which predefines verbose,
usetimestamp, username and password for the get task.
The target called from commandline is "getArtifacts" which antcall's "getJArtifacts" where
there
is a large block of 23 antcall's to execute the different get*Artifacts targets.
The get task itself communicates over SSL.

First a "reference" of ANT 1.6.2:

of using 23 antcall's (with ANT 1.6.5):
