May be this query is for Harbour User Forum, but I am posting here because IMHO, HMG people are more helpful ....

Does DFF/CDX RDD use any optimization (eg., Rushmore in FoxPro)? Are the commands like LOCATE FOR, SET FILTER etc. optimized?
(Please correct me if I should post it in another place)
Thanks in advance.
With best reagrds.
