Lame question: Would user-settable GUI refresh rate help with speed problems or with audio dropouts that some people experience? Or do these depend on the amount of data transmitted and not on the update frequency?
I _think_ this depends on the kind of GUI element. If you send thousand messages per second to a slider, then it would probably help. But you can limit the rate already now, so I personally don't think that a fixed refresh rate would urgently be necessary.
I think arrays can be quite a hog since not only for every pixel you see a message from pd to pd-gui was sent, but for every sample. This can be quite a lot of messages when you change significant chunks of an array.
You don't even have to change the array-- just displace it in edit mode. If I remember correctly, for every pixel it's displaced pd recalculates the relationship between pixels and samples to redraw the array, rather than just moving in Tk by tag. It's ridiculous.

However, a fixed GUI refresh rate wouldn't help with this.
