What do you mean by this? I'm not sure that Tim was indicating a
performance problem. Leaks can occur without abnormal levels of
swapping, especially if they are slow enough become significant
only over a span of days or months. The leaked memory will, almost
by definition, not be used again and thus will not be swapping in
and out. Unless the leak becomes a flood, it can slip under the
radar. I thought Tim wanted to see if there was a single stand-out
static consumer of swap space (hence his idea about using `ps`).
