>From what I have read I was under the impression that there wouldn't be any performance increase using INDEXSEEK() over SEEK(). I have a looping counting and totaling procedure where all I did was change a SEEK() to INDEXSEEK() with the move record pointer parameter set to .T., the time the procedure took with the SEEK() was 363 seconds, after changing to INDEXSEEK() the procedure takes 8 seconds. This occurs no matter if I reboot after each run or not, so caching isn't an issue.

Sounds interesting. May be the team never rewrote the seek function internally but the indexseek code is better.

The VFP guys seems to always get another way to increase performance! Look how SQL server performed 5 years ago and now, as a proof! 8-)
