Thanks for the quick response. I have no use of "exec" tasks in my test scenario.
VisualVM showed that AntClassLoader.getCertificates() was sucking up all the time. If I revert AntClassLoader.defineClassFromData() to what it was in 1.7.1, it resolves the performance problem.

Yes, for any <exec> type of task on Windows (this includes, for example, <attrib>) that used to take way less than a second. Currently each such <exec> takes at least a second (give or take a few millis) so if you are using a lot of little <exec>s this will sum up. The reason behind this is that Ant 1.7.1's logic could make processes hang on Windows and the revised logic involves timed joins to simulate async reads. We may get through with making the sleep interval a little bit smaller in future versions - or we may find a better fix for <https://issues.apache.org/bugzilla/show_bug.cgi?id=5003> Stefan --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@ant.apache.org For additional commands, e-mail: user-h...@ant.apache.org --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@ant.apache.org For additional commands, e-mail: user-h...@ant.apache.org
