With a small table ( 100000 records , file size 95 MB ) I see no real difference running SELECT-statement on fields with index of without index.

knamn LIKE 'LARSEN%' ( indexed field )
0.538 seconds

adresse LIKE 'ATT%' ( no index )
0.509 seconds

gateadr LIKE 'KJ%' ( no index )
0.558 seconds

knr = '0315900' ( indexed field )
0.490 seconds

Rushmore does not show at all.
I double ( to 200000 records )
Now VFOLEDB is in real trouble.

knamn LIKE 'LARSEN%' ( indexed field )
65.701 seconds

adresse LIKE 'ATT%' ( no index )
66.215 seconds

gateadr LIKE 'KJ%' ( no index )
66.614 seconds

knr = '0315900' ( indexed field )
67.311 seconds

My conclusion so far is that VFPOLEDB does not use Rushmore technology.
And that the product is useless for real business.
I will report back after testing with VFP8 SP1.
