Subj:   Re: FastExport Performance
From:   Michael Larkins

You do not specify the number of rows to return, nor do you tell us how many sessions you are requesting.

Characteristics of FastExport:

1. If too many sessions requested, it can take longer to logon all sessions then it does to retrieve the rows. Start with 2.

2. If a small number of rows (<500,000) retrieved and ORDER BY used, it can take longer for FastExport to build all the sequential 64K blocks than it does for BTEQ to SELECT and retrieve all rows.

Hope this helps,
