what's mean waitport/waitmsg

[k simon]

Hi,   Ziehau

   Yes, you are right. Not only netisr_cpu 2, and netisr_cpu 0-7 else.

And my box’s version
# uname -a
DragonFly sq-l1-n2-df 3.4-RELEASE DragonFly v3.4.3.16.g5011f5-RELEASE #0: Wed Oct 23 16:44:28 CST 2013     root at sq-l1-n2-df:/usr/obj/usr/src/sys/MYKERNEL  x86_64

    As a high load for IO and network load system, can I tuning something for make it better?



# cat /boot/loader.conf
kern.ipc.nmbclusters="262144"
kern.ipc.maxsockets="204800"
## tuning for tcp
net.inet.tcp.tcbhashsize="262144"
net.inet.tcp.reass.maxsegments="16384"
net.inet.tcp.syncache.hashsize=32768
net.inet.tcp.syncache.bucketlimit=32
net.inet.tcp.syncache.cachelimit=1048576


# cat /etc/sysctl.conf
kern.maxfilesperproc=500058
kern.ipc.somaxconn=65532
net.inet.ip.portrange.first=10001
net.inet.ip.portrange.last=65535
net.inet.tcp.msl=5000
net.inet.tcp.syncookies=0
net.inet.tcp.sendspace=32768
net.inet.tcp.recvspace=32768
net.inet.tcp.recvbuf_auto=0
net.inet.tcp.sendbuf_auto=0
net.inet.tcp.tso=0
kern.metadelay=3
kern.dirdelay=4
kern.filedelay=5
vfs.write_behind=0
vfs.ufs.dirhash_maxmem=16777216
