A friend of mine has an app where some animations are done by flipping
through cards. Speed is variable, set with a "wait <n> milliseconds"
statement, so the user can view the sequence as quickly or slowly as
desired.
In versions up through 6.x the speed was quite good, but in v7, 8, and 9
the speed drops below acceptability.
We did some tests and oddly enough the problem doesn't seem to be with
card rendering: when we comment out the "wait" statement speed is
pretty good. It's maybe a tad slower perceptibly, but still good enough
for the animation to be viewed meaningfully.
But "wait 1 millisecons" or even "wait 0 milliseconds" takes FAR longer
in recent versions than in v6.
He has no "...with messages" clause, so any extra time needed for the
event loop should not be a factor.
Something seems amiss with the "wait" command itself.
He's sending me his stack file so I can winnow it down to a good test
case, but in the meantime I wanted to ask here:
Have any of you seen unusual delay with "wait" statements in versions
later than v6?
