A few days ago I posted some numbers that compared the build times between Boost.serialization and Ebenezer Enterprises. http://lists.boost.org/Archives/boost/2005/11/96781.php Since then I realized I made a mistake in those tests. Originally, I said it took 42 seconds for the Boost version of the "list<int>" test to build. That should have been 27 seconds. I had a file included in the original test that was not needed. The time with the webEbenezer version didn't change - it is 12 seconds. I rechecked the "list<int> and deque<int>" test and those numbers didn't change. Sorry about that. Brian
