My problem is this, the data is on a NT 4 box and I have 2 do queries/subtract info out of this table. I'v tried SELECT but that was realy very, very slow. Then I used the SET FILTER. A lot better, but far to slow.

The Computer i'm using for this is a Pentium 133 with 64 MB. How much improved performance will i be able to get say on a P2-400 with 254 MB memory, will this realy solve my problem.

Moving to SQL Server is also a possible root to go. The problem is i dont know SQL at all and i Do not know if iit will be any faster at the end of the day.

PLEASE help.

>If we're talking just speed...you'd probably have to run some tests, and then it would also depend on your coding style. Some firends at work were having a debate over the performance (speed) of Append Blank and Replace, vs. Insert. It was surprizing to see the on the first round of implementations X was faster than Y...on the second round of implementations Y was faster than X...on the third round of implementations X was faster than Y...
