He's probably noticing that Awesome doesn't have the lag and jitter problems that compositing window managers have, and is erroneously attributing it to the small footprint.

From a user's point of view it's very reminiscent of the bad old days when swapping was common. But don't worry guys, even Windows 7 and Lion (Apple has been working on the compositing thing for what... ten years now?) still stutter and stall just like Compiz. I'm sure it will be like this forever.

Indeed, what you point out about lag is true. Look no further than this: http://blog.martin-graesslin.com/blog/2011/08/rendering-a...

Although machines may look over-specced, we still get various lags introduced by drawing. For example one thing I seem to replicate frequently with KWin is starting a high resolution video full-screen, and running KSysguard at the same time: the video will stop for a short instant every second, with metronome regularity. Fortunately at least memory is cheap enough swapping is history.

I guess these disappear only after you take every code path and ensure none takes takes more than a fixed period of time, in a sort of RT systems fashion.
