What about dropping the saved data from the large data set - if that is 
allowed in your application (no overlap between data-slices).

I mean you could do the following:

***************************
use <somedata>
preserve
keep if <somecondition>
save <sliceofsomedata>
restore
drop if <somecondition> 
preserve
...
***************************

wouldn't that increase speed because the original data set gets smaller 
and you save a last preserve?
