I haven't had enough experience with Informix yet to determine the extent of the scalability, but I have worked enough with Sybase to know that if you could get 2500+ users online the performance would be very poor without a TP monitor. SMP hardware is especially well suited for large scale OLTP. -- //////////////// Mark Sigler ////////// // Client Services Engineer ////// / /// Informix Software, Inc. ///// // //// 8675 Hidden River Parkway TBD //// // ///// Tampa, FL 33637 Fort Lauderdale, FL /// // ////// Voice: 813.971.0010 407.883.9319 // // /////// Fax: 813.632.9582 407.883.9319 / /////////// Voicemail: 800.688.4217 x2147 407.883.9319 //////////////// Email: msigler@informix.com WWWeb: http://www.informix.com --
