IIS 3.0 is apparently a bad performer (well, a worse performer than IIS 4.0, anyway) and takes more time to recover. Did you run these tests on the same computer (or at least on ident- ically configured computers)? If not, there is no basis for comparison. DES -- Dag-Erling Smørgrav - dag-erliat_private
