Max Brunning has posted a brief comparison of how these three Operating Systems approach a number of basic kernel tasks. He has a brief look at: Scheduling and Schedulers, Memory Management and Paging, and File Systems. Max is an Instructor who spends his time teaching Solaris internals, device drivers, and kernel crash dump analysis and debugging.

Well you think wrong because the IO cost of swapping far outweighs the page fault cost. A healthy running system should not be continually swapping.
Shows how much you know.
hmm... no it actully shows how incredibly stupid you are. Most reasonable people would chase down big performance bottlenecks not little ones. Therefore, I said those matter most.
Err, what do you mean "right". You just tried to claim that protection faults are only triggered on an illegal memory access from the application. Don't try to say "right" as if you meant something else.
No.. I meant to say "right" to imply the inconsecquentiality or your absurd claim. You are too caught up with yourself to know it.
And no, they don't only matter for fork performance. As I said, they matter for some types of memory allocation in linux, and also virtual machines and garbage collectors.
Hunh?? Say What? what type of memory allocator and garbage collector reiles on protection faults????
'page fault'? Yeah Linux beats Solaris hands down on that too.
Data to support that???? Your data or URLs are outdate and useless. Move on.
<I.Err no, see the URLs I provided. They are real numbers and the only claim I made was that Solaris running a machine 3 times faster only just managed to catch up to Linux, which was shown in the numbers. [/i]
No you dufus.. your data is worthless.
You've done nothing but spout a load of drivel and pretend to know something about operating systems that you don't.
I happen to write kernel code for a living and get paid very well for it thank you.
