Out of interest, could this parameter of 20 be automatically tuned based on the
available RAM?

For systems with a lot of RAM, it might make sense to increase the parameter
above 20 (assuming this produces better code in the end).

Whilst they could override this using the flag mentioned in comment #3,
auto-detecting this parameter would make it easier for the end user.
