Ordered facts like this lead to slower matching and higher memory
consumption than unordered facts (i.e., facts with named slots.)
Multislots in general have the same effect compared to single slots.

Don't use function calls when you can do direct matching. This doesn't
effect performance, but it effects speed. Instead of the above, write
?wheat <- (MAIN::wheat (position ?wheatPos&~?workerPos) (OBJECT
?wheatObj))

I assume you've read the manual and so already have played with
set-node-index-hash (both the function and the defrule declaration?)
These can have a dramatic constant-factor effect on memory usage.
