The tables could just as well be       spread over all 30 files. But the busy part of the tables could be       in those 15 files.              I don't what is in your tables, but in the system I work with, this       is likely to be true. We have transactional tables that holds transactions       several years back, but most of the queries are of course related to       recent data. Not talking about inserts.              Indeed, getting a perfect mix over all 29 SAN mountpoints is a real       challenge.                     --       Erland Sommarskog, SQL Server MVP, esquel@sommarskog.se              Links for SQL Server Books Online:       SQL 2008: http://msdn.microsoft.com/en-us/sqlserver/cc514207.aspx       SQL 2005: http://msdn.microsoft.com/en-us/sqlserver/bb895970.aspx       SQL 2000: http://www.microsoft.com/sql/prodinfo/previousversions/books.mspx              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
