I am using the PHPUnit framework to write testcases for execution on the Selenium RC server. The PHP scripts and the selenium server are running in the same machine. I have written some functions like reading of XML files, command like parameters, XLIFF integration etc by extending the PHPUnit_Extensions_SeleniumTestCase class. But the problem I am facing is that the script runs very well in Windows, but it runs very very slowly in linux and timesout after sometime. In linux the browser opens in the console I can see that there is a long gap between the selenium commands (for e.g. after the 'open' command, it takes a minute for the next 'click' command to appear on the browser) Has anyone experienced this problem before ? If this is not the right mailing list to post such a query, could please you suggest some other mailing group.
