which I wasn’t using. It is preloaded with about 10 rows of gateways. I
use the dm column to keep a count each time the gateway returns a ‘busy’.<o:p></o:p></span></font></p>

the table. The time to select grows from sub millisecond to > 100 ms.
Analyzing the table, I see the number of index pages grows to thousands (table
is still 10 active rows).<o:p></o:p></span></font></p>
