Here's what I did. I simply added a new variable called 'fooList' of type StringList. Then I inserted extra Create() method calls: //these lines are simply to test the CPU load of the Create() method fooList.Create(config->Find(&aUrl, "exclude_urls"), " \t"); fooList.Destroy(); //these lines are simply to test the CPU load of the Create() method fooList.Destroy(); fooList.Create(config->Find(&aUrl, "bad_querystr"), " \t"); fooList.Destroy(); Then I re-compiled and ran with my normal excludes URL list. It didn't seem to have much of an impact on performance. This means that the performance hit is definitely in the HtRegexList::setEscaped method.
