I have a Leopard system which feels rather sluggish, and which I suspect may be disk-I/O-bound. While I know how to check which app is using CPU or memory (top or Activity Monitor), I don’t really know how to check which application is heavy on disk-I/O, or if (and how much) swapping occurs on my live system.
So, is there any application out there that would monitor and report disk I/O operations for me (in whatever unit is relevant)? Same for swapping: how can I check if (and to what extent) my swap memory is used?
