why is the script profiler saying this line takes 4765 milliseconds top execute?


If it's like the MC profiler, these are relative times. They aren't 
meant to tell you exactly how long an operation takes, just how it 
compares to others. The profiler itself slows down execution.

It may also help to lock the screen for visual effect within a given rectangle, 
thereby reducing the number of pixels that need to be updated. If the images 
are of equal dimensions and with the same loc, you can refer to the rect of one 
of them, otherwise you can have an invisible graphic as reference or just the 
local screen coordinates where you would like the effect to take place, like 
this:

lock screen for visual effect in rect(rect of image “test1”) — or the direct 
coordinates as param (200,200,500,400)
hide image “test1”
show image “test2”
unlock screen with visual effect dissolve very fast

So: if the effectRate defaults to 2000 (which is what I'm seeing here on 
desktop) and you have

# theoretically 1/5 of 2000 = 400 milliseconds

why is the script profiler saying this line takes 4765 milliseconds top execute?

The dictionary has two methods: if you look up "show" it appears you should be 
able to perform this "directly"

But, under the visual effect command the suggested method is to lock screen, 
make the change then unlock the screen with visual effect.  And we get 
different results, various conditions where the effect just does not happen 
anyway…no fadein as expected… there is a delay… screen is "stuck" and suddenly 
the image changes.

hopefully this all improves very soon as CSS Animation which is fast and 
smooth… now dominates UI everywhere, even for small inconsequential UX ops… 
designers are expect all kinds of "oozing" warp,slide,fade away etc.

Frankly I'm sure users care that much, and if you have a very strong content 
component, it's a lot more compelling than having your address book "zip up" 
when you close it.  And what I'm here is that the most important thing is 
stability and performance. So, I may just remove all these dissolves.

Effect durations can be normalized and fine-tuned using the effectRate

Dissolve/Transitions Very Costly

[Sannyasin Brahmanathaswami via use-livecode]

Appropo optimization thread, I'll dig in on specific issues

The script profiler is showing this

for a script that runs super fast until:

1433 868 show image "gems-image" with visual effect dissolve very fast

So this was pertty long but I suppose reasonable enough…

then, I  ran it again.


1433 2526  show image "gems-image" with visual effect dissolve very fast

Yikes!  2.5 seconds for dissolve very fast on a 120k image…

given the new look and feel of apps where transitions are *everywhere* … this 
takes waaay to long…

is there any way to optimize this?
