DEVICE_POLLING IF_EM CPU usage

Hi, I activated polling in 8 interfaces em0... em7 (ifconfig em* polling) to carry through performance tests, when activating, it had a significant reduction of CPU usage, load average measured of 0,50, 0,69, 0,52 for 0,43, 0,39, 0,21 and the CPU usage (SNMP Graphic) measured of 35% for 5%.

DEVICE_POLLING vs. SMP kernels

I am contemplating using the DEVICE_POLLING kernel option with an fxp NIC on FreeBSD 5.3 using an SMP kernel. /usr/src/sys/kern/kern_poll.c clearly states that DEVICE_POLLING is incompatible with SNP kernels: #ifdef SMP #ifndef COMPILING_LINT #error DEVICE_POLLING is not compatible with SMP

DEVICE_POLLING in 5.3

Hi fellows, I'm trying to tune network performance of a 5.3-BETA5 box by compiling the DEVICE_POLLING and HZ=1000 options into the kernel. Compilation went fine. I found the usual warning in /usr/src/sys/kern/kern_poll.c concerning device polling in SMP kernels and removed it. To finally enable

DEVICE_POLLING on Intel HT systems

I tried recompiling the kernel on a 5.3-beta2 box with DEVICE_POLLING enabled. Compilation failed with a message saying DEVICE_POLLING isn't compatible with SMP. Luigi says on: http://info.iet.unipi.it/~luigi/polling/ Why does this code not work with SMP ? It actually might work (if you remove

Device_Polling Network Cards

Does anyone know what network cards can take advantage of device_polling? I already am aware that these cards/drivers can use it, but I am wondering if FreeBSD 4.8/4.9 specifically support more network cards know. Thanks in advance. * dc -- DEC/Intel 21143 and clone 10/100 ethernet driver * fxp
