seconds to process any of your SELECTs.
> Is this overhead due to MSSQL changing the
> concurrency ?
No. The overhead is due to MSSQL being brain dead and doing a full table scan
to process your SELECT statement. MSSQL does not use non-unique indexes
when processing SELECT statements. There are four ways to get decent performance
out of your system:
1: Get rid of MS SQL and upgrade to a decent SQL system
like SQL Anywhere or any other SQL
2: Upgrade to MSSQL 7
3: rebuild your indexes so they are unique
4: Do everything using PROP:SQL to send a SELECT with the
(index=) hint
