No, process list is very short, it is custom semi-embedded linux distro i
made, so i know each process running there. Here is process list (kernel
processes/threads and running shell(busybox ash) removed)
I dont think i am alone, and almost sure there is many guys trying to run
linux as high-performance router. But most of them dont know about
netdev@ :-)
Well, thats called "Increasing resources use efficiency and system
productivity". It is never a shame to utilize resources more efficiently.
Plus i am not using PC class machine. For example this one with HPET, is Sun
Fire X4100, which costs us that time a lot of bucks, and mostly because it is
reliable hardware (very good IPMI/remote kvm/... onboard, good cooling, 4
e1000, dual power supply).
I can use also PC class, but i will face some issues, like building proper
cooling system and maybe even it will not work well, cause some chips not
designed for "heavy duty", and on load they will not be able to dissipate
heat inside the chip and will be broked soon. But sometimes it is even worth
to try.
And most important, many routers is already "soft"-routers. What is Cisco
7206+NPE G1/G2? It is MIPS CPU with relatively large L2 cache. There is seems
no ASIC for routing offloading. Means Linux can do same or better job.
And means Vyatta can beat Cisco on this market, and be far away forward from
Cisco soon. As result more jobs for opensource guys. Linux must enter "heavy
duty" and critical jobs too, not only SOHO-class routers.

I think it wouldn't break. But sure we must be very careful and on my side i
can test all possible scenarios i can implement.
Maybe even good idea to not change (for now) current default behaviour, but
to provide option for "high performance" systems then.
