Please...when posting to technical forums, be specific as to levels. Your AIX 5.?.?.? probably is not current, and is suffering TCP/IP performace problems as has been noted by multiple posters over the past months. If your AIX is up to level, the standard advice is to perform benchmark measurements of your network performance, in concert with your site network people, to help isolate the problem area. You should not immediately attribute network throughput problems to the application (TSM), which may be the victim of opsys issues or network hardware/configuration. Richard Sims, BU
