I've had some pretty unusual communications over the years (for example "Dear Mr. The Hutt. Why did your mother call you Javva? That's a very odd name."
"I tend to rely on what some would regard to be very primitive tools. If I could equate favorite to most useful then I would have to pick vmstat. Now you may think that it is funny that a tool that spits out kstat values would be so useful in performance tuning Java, however you can use it to eliminate entire classes of problems in just a few minutes. If you are looking for a needle in a haystack the best thing to do is to get rid of as much hay as you can up front."
