Revolution much slower then Hypercard

I haven't noticed any significant speed difference in my own use.

Not knowing how many cards you have or how much data in each field, I 
created 263 cards (via a script which created a card for each line of 
some text I grabbed, happening to be 263 lines) putting random chunks 
from each line into three fields. Then I executed your scripts with lock 
screen off and on. HyperCard was in Classic 9.2 and Rev in OSX. You 
would expect Rev to suffer in this comparison because OSX will interrupt 
it more than HC will suffer in 9.2, I expect (I had several OSX apps 
open at the time, including a mail collect). Results were:
screen unlocked - HC 8.1 secs, Rev 8.5 secs
lock screen - HC 0.15 secs (!), Rev 0.9 secs
So Rev was dumped on by HC in the lock screen state but there is nothing 
even remotely resembling your differences. There is something there you 
have not told us but the good news is it should be resolvable.
