Hi everyone,
I have a working script deleting a lot off tags of several mio (yes your read right Millions) objects, but need to optimize the coding.
I want to code a stopwatch at start and end of the code so i can measure my improvements in code - how do i do that?
Also what can I do to make my script faster (stripping all undo code?)
kind regards
mogh

You can call GeGetTimer() to measure the execution time of your code. See the code in this post.

Yes, you could try removing your undo code.

Just had this idea, but it comes with a little more code than I had expected. However, maybe you can find use for it.

There are a few good tips at the French forum here:

And yes, for very large set ups, skipping the Undo totally can help - a lot-
for speed in that your ram isn't filled with undos.
For some of my PLA scripts/plugins calculating 10s of thausands points per frame
I simply set the main undo to minimum (1) while they are running, resettings
the main undo after they're done.
Cheers
