[PD] Textfile vs. Lists vs. Arrays vs. ?

[Oli44]

I solved this problem by copying the files in RAM, on a virtual disk, 
prior to  playing from the patch.

On Linux, I have a shell script that copies  to  /dev/shm  then symlink  
to the folder where the patch resides, then start pd and it runs smoothly.

As long as your files dont take up much space in memory, it's fine. 
Otherwise, they shouldn't sum up more than half the total RAM of your 
machine, otherwise it swaps.

I have no idea how to use this technique with Win/Mac.

(I've put all the graphic-heavy stuff into a subpatch which remains closed during live playback as my initial feeling was the glitches were caused by graphical stuff as is usual with pd. But surely once in a subpatch and closed there's no overhead?)
