Cache frequently used functions and objects

MAXScript FAQ > How To Make It Faster > Cache frequently used functions and objects

You can store frequently used functions and objects in user variables to faster access.

TEST CASE: 

ep = converttopoly (mesh())    --node
ep_bo = ep.baseobject      --ediable poly
polyop_getvert = polyop.getvert    --structure method
IEditablePoly = ep_bo.EditablePoly   --FPS interface
IEditablePoly_GetNumMapChannels =
IEditablePoly.GetNumMapChannels   --FPS interface

FOR 100,000 ITERATIONS: 

polyop.getvert ep 1    -- 470 msec.
polyop_getvert ep 1    -- 79 msec.
polyop.getvert ep_bo 1   -- 48 msec.
polyop_getvert ep_bo 1   -- 0 msec.
ep.EditablePoly.GetNumMapChannels() -- 76532 msec.
ep.GetNumMapChannels()   -- 72141 msec.
ep_bo.EditablePoly.GetNumMapChannels()-- 36688 msec.
ep_bo.GetNumMapChannels()   -- 34219 msec.
IEditablePoly.GetNumMapChannels() -- 6454 msec.
IEditablePoly_GetNumMapChannels() -- 0 msec.

TEST CASE: 

gs = geosphere()
gs_bo = gs.baseobject
theBend = bend()
addmodifier gs theBand

FOR 100,000 ITERATIONS: 

gs.radius     -- 718 msec.
gs.baseobject.radius    -- 828 msec.
gs_bo.radius      -- 688 msec.
gs.modifiers[1].angle    -- 718 msec.
gs.modifiers[#bend].angle   -- 1187 msec.
theBend.angle     -- 609 msec.
