Geo,

Is Rushmore smart enough to re-use the bitmap from your first LOCATE when it does the second LOCATE? Since you're not closing the table in between... maybe?

>>Hey George, I've tried to duplicate your results, but I cannot. With the tag set I'm getting 36 seconds and without it I get .29 seconds. This has always been my experience. There was even a time when it was recommended that you SET ORDER TO 0 before running an SQL, but that's not necessary anymore. Here's how I created my table and how I tested the performance ... I hope I got the UT code formating stuff right.
