i think this is one of those philosophical areas where a decision one way or another needs to be made.
other commercial unix systems (hp, sun, ibm, sequent) tend to split into two camps as follows:
1. those that optimise for performance, but degrade badly under intense load.
2. those that optimise for intense load, but don't have top-notch performance under low-load.
now, my bias is towards #2, because i am more interested in server systems, and from a sizing, tuning and sysadmin perspective they are easier to plan and manage. however, this is probably not the right thing for a desktop operating system.
so, which way is linux going? you tell me - there doesn't seem to be a "right" answer here. this may well mean there needs to be two schedulers, one with ultra-low overhead for desktops, and another, with better scalability, for servers.
