If I may:
this version (the 2022c candidate) contains vast improvements in the
way user-written functions are handled internally. This should
translate into a sizeable speedup of certain feaures. For example,
addons such as gig or SVAR should be much faster, and the same should
happen to function packages like CUB, DFM, MGARCH or StrucTiSM[*].
I tested my own MSVAR package on gretl 2022b against today's snapshot,
but for a certain specification I did not see any performance gain, I
must say. If I understand correctly, user-written functions that are
called in a nested way (and/or within a loop) would benefit the most.
Perhaps that's not what the MSVAR hansl code does, I haven't re-checked.
Jack, maybe you could give a concrete example (with our StrucTiSM,
perhaps?) of what kind of gains we're talking about.
