[PD] Ways to decrease processing delay?

Hi,

I'm a beginner using PD as a realtime MIDI processor, and with the help of this list, I've been able to prototype my application in just 2 short evenings.

Now, I'm looking to make my app as tight and fast as possible.

I've used the minimum amount of code whenever possible -- it's probably not as elegant as it could be, but there are no apparently obvious gas-guzzling portions of code. (It does use 2 subpatches, I don't know if those are slower or not.)

Also, since the app does not require audio processing, I used the -noaudio flag. I tried using the -nogui flag but it doesn't seem to work at all then.

Here's a link to the app if anybody wants to take a quick glance at it for any glaring problems:

Thanks, rs
