Well, that's true in a left-handed way.

Systems of the SVR4 lineage don't *need* as much kernel tuning.  They're
highly dynamic and can efficiently shift resources - such as memory - around
on demand instead of requiring the system administrator or some program
to figure out that "ooooh, you need more hash queues; let me turn up that
number, build you a new kernel, and remind you to reboot".   You don't have
to decide at kernel configure/build (or boot) times that "I want 18.73 
Megabytes dedicated to disk buffers even though I know that memory can 
never be used by user applications".    The system doles out pages where
they're needed and doesn't require the admin to turn knobs.


More to answer the original question for UW7/OU8, check out 'rtpm'.  It
shows you where resources (cpus and memory) are being spent in a realtime-ish
format.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
