I would say that once the UI has been shown it should be kept up-to-date with the typing at any speed.

The context was in terms of avoiding unnecessary repaints because of the bandwidth consumed. If it's an unacceptable performance hit it's an unacceptable performance hit independent of whether the user pauses or not. It's fine, though - it turns out that Gnome doesn't wait for any drawing to be carried out before responding to keypresses. You're free to interact with it while it's redrawing things.

The thing is, if you want to come up with some absolute standard of when a performance hit is too much, you have to make way too many assumptions to do so. A slow user on a fast system will need all the help he can get - while a fast user on a slow system is going to want to throttle you if the computer seizes up trying to do searches and display suggestions when he knew what he wanted. There are going to be a whole continuum of use cases and explicitly tuning for one spot on the spectrum detunes all the others.

Simply waiting for a break in the input before triggering (and thus not triggering at all when input is fast and complete) gives you a kind of autotune for all kinds of cases. I am not talking about a long pause, just a momentary hesitation. Even on a new computer a fast typist can sometimes get ahead of the display, and on a slow machine it isnt hard at all to do that. Once it's all caught up and hits an idle loop, you can worry about whether it might make sense to make a suggestion.

What are you defining as a slow system? I haven't found any hardware that runs Gnome 3 that is unable to reasonably keep up with my typing.

I like Gnome 3, but my crappy netbook (Acer Aspire 522, all AMD parts) is pretty slow. If you have a couple of applications running it can take more than five seconds after you write "firef" in the overview and the Firefox icon shows up.

My iMac was much faster, but that can't run recent Fedoras (https://bugzilla.redhat.com/show_bug.cgi?id=865031)
