slow performance and crash

I am building an experiment with Open Sesame.
It feels like each time i fill in an item performance is slower.
When i try to delete unused items it even crashes and i have to shut it down. Reopening also takes a lot of time.
Experiment size is only 360kb.
Of course i have a lot of loops and sequences. But i need them. That's inevitable.

Any ideas what causes the lag?

  • Could you upload the experiment? That way I can see where the lag comes from, and possibly optmize it in future releases.

    There's much bigger issues in the world, I know. But I first have to take care of the world I know.

  • I am not sure what kind of files to upload. I tried to open this file on a second pc, but there it does not open. Nevertheless, i hope you can open it. ;)

  • Thanks! I'm going to see if I can pin down where the lag comes from.

    I'm afraid that I cannot provide an immediate solution though, other than reducing the number of items (98 is a lot!), possibly by using variables instead of creating a new sketchpad for each display. Or by using a script.

    Also, what did you do with the experiment before attaching it to this post? The encoding of the script was changed from utf-8 to something else. I could open it by manually extracting the script and changing the encoding back. But OpenSesame doesn't save it that way.

    Cheers!

    Well, actually 98 items is not that much for our kind of experiments (motor control).
    But i will try to put it all in a script. In the script i have more options anyway. Only that i have to learn python now ;)
    Where do i put the script? Can i write all into the general script (or at least the definitions) or do i need an inline_script?

    I did not do anything special with the file. I saved it with "save as". The only option there is an open sesame file. That's it.

  • I uploaded a prerelease (>= 3.1.3a4) that contains at least optimizations that should speed things up a lot in some cases, such as when emptying the unused-items bin.
