We generate multiple pom.xml files from pom-template.xml in the project directory. It comes down to substituting several version properties. The substitution is done in create-poms.bat/create-poms.sh script. SED is used on both platforms. Unix substitution goes well - no problems are encountered. On Windows however there is a problem: if run locally substitution gets done in about 10-15 seconds; if run in QuickBuild, the substitution runs for about 27 minutes.

I cannot get to the cause of this performance issue.
- we use sed.exe from git 1.7.4;
- tried running create-poms.bat directly without Ant - no improvement;
- tried first generating the list of poms to convert, followed by processing the list - no improvement.

Please advise how to approach the issue.
Thanks.
