"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."

We used the sarcheck product this year during website app performance testing. Although no substitute for rolling up one's sleeves and getting a PhD in man pages and tuning textbooks, it did offer a quick kill solution. Note that I just used the product, I don't sell it.
"SarCheck is an inexpensive tool developed to help system administrators with UNIX performance tuning. It does this by analyzing the output of sar, ps, and other tools, and then reading more information from the kernel. It then identifies problem areas, and if necessary, recommends changes to the system's tunable parameters.
