This is a case where "bigger is not always better". In this case, the reason for the recommendation is because Windows's disk I/O buffers are smaller than the buffer we use when LARGECOMMBUFFERS YES is in effect, so we end up waiting on the disk I/O to fill a buffer before sending it to the server, causing serious performance degradation.

If you do not do this, then some of the files will not be updated "in place", and you will be prompted to reboot in order to pick up the changes. As to the performance problem, there are no other changes you need to make to make it work, except, that in general, you should always avoid using LARGECOMMBUFFERS YES on Windows Regards, Andy Andy Raibeck IBM Software Group Tivoli Storage Manager Client Development Internal Notes e-mail: Andrew Raibeck/Tucson/IBM@IBMUS Internet e-mail: [EMAIL PROTECTED] The only dumb question is the one that goes unasked.

This fixtest appears to also fix the RC 4 probem and the performance problem. Can you tell us a little more about the performance problem fix. Are there any changes that we might want to look at besides installing the fixtest. PS in the readme file it says that for an uninstall of the client, one should stop the tsm services first. Should this also be done if doing an upgrade. An upgrade from 4.2?
