Try using the <for> task. The <foreach> task has the overhead of having to re-load the build file as it runs the target. The <for> task uses macrodefs and should be much faster. Also if you have such a well-defined complex usage it may make sense to create a custom task and drop into a compiled language (like JAVA) to accomplish what you need. Ninju
----- Original Message ---- From: Ephi Sachs <[EMAIL PROTECTED]> To: user@ant.apache.org Sent: Tuesday, December 13, 2005 11:53:41 AM Subject: ant-contrib foreach performance I have a <foreach> task which runs on a list of >1000 strings, and calls an ant task which extracts 2 sub-strings, interprets them as numbers, calculates their sum, and replaces the 2 sub-strings with their sum (this is done by writing the sub-strings to a properties file, loading it and using the <math> task). The problem is that running the <foreach> task so many times, even on an empty task which doesn't do anything, takes a long time (over a minute). So: 1) Is there a more efficient way to accomplish iteration over a list? 2) Is there a way to perform such a math operation in a regular regex replacement, without using a foreach iteration?
