Satish Gidugu (VIP) I posted this problem originally on the xml group. I have an app that processes XmlDocument and uses XmlElement.GetElementsByTagName quite liberally for various operations. It appears that the XmlNodeList (actually a subtree) returned by this method internally hooks itself to the document's NodeInserted and NodeRemoved events. After a while, inserting an element into the document takes close to 12 seconds on a PIII 1.8GHz 512MB machine because each instance of the XmlNodeList is notified about the insertion. All references to the XmlNodeList are only local variables with method scope. Q1: Is there some way I can clear the listener collection of the XmlDocument's events? Q2: Does forcing a GC.Collect() help in these kind of cases? I currently clone the XmlDocument at regular intervals to keep the performance reasonable. This makes the app run 25 times faster. many thanks, Satish Reply to this message...        Dmitriy Zaslavskiy GC.Collect will not help. It's kind of by design. Also consider using XPathDocument instead as it solves this and other problems. "Satish Gidugu" <Click here to reveal e-mail address> wrote in message news:Click here to reveal e-mail address...

This approach probably is not recommended but if you have no other choice you can use it.
