Relatively speaking, yes. Running both forms through MetaBench verifies
that indeed "the owner of me" is about 80% faster.
But considering that parsing the long ID only takes 0.0022 ticks to execute,
the flexibility will probably be worth a speed difference not likely to be
noticeable by humans, at least as a workaround until we see the long ID
returned (2.4 GM maybe?). 'Less of course you've some reason to run this
several thousand times in a row, but even then the fast thing to do would be
to parse it just once and then store the parent's long ID in its own var.
These are the scripts I ran in MetaBench last time I looked into it (on a G4
500):
get the owner of me
4 ticks to execute 10,000 times (0.0004 ticks/iteration)
get the long id of grp ID (word 8 of the long id of me)
22 ticks to execute 10,000 times (0.0022 ticks/iteration)
