The slowdown I notice is on a single-core 512Mb machine, and I haven't
looked into full system statistics for it but the behaviour is
consistent with thrashing virtual memory... after editing for a while,
drawing ways with the mouse gets very slow (almost freezes); I think I
found the browser process had got very large, but I can't remember. I
just guessed that the code to search for whether the mouse was
currently on an existing node was looking through more stuff than
would fit in RAM, that was what the behaviour "felt" consistent with.
I can investigate further if you like, but are people concerned with
such small machines (other than as thin clients) these days anyway?
(It might be of concern for mappers in poor countries getting
second-hand machines, for example.)
