    There is a multi-server network that has been humming along for a couple of years. The document store is on a NetWare server; the document management index on a Windows NT 4.0 Server; and the indexing process runs on an NT Workstation. The indexing process involves reading through the document store, writing a temp file on the indexer, and writing the final out to the NT Index server.

    A complete rebuild used to take about six hours for profiles (named fields) and full text. Then the NetWare server was replaced with a newer Compaq Proliant, and re-loaded with the same NetWare 4.11 operating system. Norton AntiVirus was added, but subsequent to the event noted below:

    AFter the new server was in place, the first pass at indexing took over 40 hours. We changed indexers, moving to the same switch, and got it down to about 13 hours. We are trying to split the profile and text indexes so that more variables are consolidated on one server.

    But here's the corker: NT Performance Monitor and NetWare metrics stayed nominal throughout the process! Nothing indicated backed up writes, or excessive paging, or collisions, or anything else related to drive channel or traffic. I'm thinking, pending further tests, that it may be an auto-negotiation issue with the new server and the switch. Any other suggestions?

    This is what makes this stuff fun, right?
