BTW, in worst case (I used ping -f, just can't find anything useful to generate many small packets) "re" generate about 5000 interrupts. While "vr" on same machine can do about 20 000 interrupts and the machine still stay. > As you can see my i386 had mbuf and mcluster failures because I run the > kernel out of kvm (this would not have happend if I increased > kern.maxclusters a bit more carefully). > Anyway, you need to properly tune your system to handle 1000 and more > TCP connections.
