Anyone using device polling on 6.2stable (i386) ?
I have been reading up on this and seen some good and some bad but
nothing definitive.
I have bge NICs in these machines and they are running as routers,
and running pf.
When I enabled it in the kernel and then via rc.conf (since sysctl
use is depreciated now) ...I can see a difference in "vmstat -i"
presuming thats the correct way to check.
With polling DISABLED...vmstat shows ever increasing values for example:
vmstat -i
interrupt total rate
irq4: sio0 3 0
irq6: fdc0 10 0
irq14: ata0 12210 0
irq15: ata1 78834 2
irq22: bge0 430416 11
irq23: bge1 917826 24
cpu0: timer 75098549 2000
cpu1: timer 75092636 1999
Total 151630484 4038
and when I do a large network operation (like ftp an ISO) it
increases and increases....however, with device polling compiled and
configured (all default values though in sysctl) - I do not see an
increase in vmstat numbers for the nics...I figured thats good...but
I might be wrong?
I dont do anything higher than WAN(10MB) and LAN(100MB).
But if anyone has any suggestions or comments -especially values to
adjust in sysctl, please chime in.
TIA
-JD
