[bug] Max 5 buttonflower example patch uses 90%+ CPU


    Apr 23 2008 | 11:45 am
    Thanks for the great work on Max, lots of exciting stuff. However, I noticed what seems to be a bug with scripting.
    When looking at the Max/examples/max-tricks/buttonflower.maxpat patch in Max 5 the patch uses sometimes 90% or more of my CPU than with on 4.6.3 (MaxMSP 4.6/examples/misc-max-trix/buttonflower.pat) which only uses around 36% max. With this patch open in Max 5, my computer gets almost completely unresponsive. I'm using Mac OS 10.4.11 with a 1.67 Powerbook/2GB RAM. I'm using Activity Monitor on OS X for my CPU percentages. Can anyone reproduce this?

      For me, only 22 % CPU at the maximum with the buttonflower (with a MacBook Pro 2.33)

      on a win desktop with e6400 processor if the toggles go outside the screen, not over 22%. otherwise 4-8% btw. thats some crazy shit

      must be a G4 thing - my iBook (OS X 10.5.2, 1.33 Ghz, 1.5 GB ram) hits 82 - 88% CPU when buttonflower is running.But the boot time for MaxMSP 5 is much, much snappier!

      So is it only scripting which is affected for you, because on my end (G4, 1.67, 10.4.11, 2GB RAM) many patches (same patch file) are using sometimes double the CPU % amount in Max 5 when compared side by side with 4.6.3.

      Almost 60% CPU in MAX5 here. Around 17% in max 4.6. I'm on a Macbook pro 2,33mhz. That's quite a difference.

      Patches that script objects to move around in the patcher (especially outside of the window bounds) are going to be slower. Not much is going to be done about that. Good news is that this is rarely done except in purely illustrative examples such as that one.
