A while ago, putterman asked Suresh and me to see what memory and performance gains having random access enumerators would give folder loading. Here are the results of that work http://www.mozilla.org/mailnews/Random_Access_Enumerator_Hack.html That page has a link to http://www.mozilla.org/mailnews/Memory_Footprint1.html, with all the raw data that Suresh gathered. If you have questions or comments, send them directly to me and I'll update document. -Seth
