The drawback is a moderate (up to 1/HZ seconds) 76# potential increase in response times. 77# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 78# to achieve smoother behaviour. 79# Additionally, you can enable/disable polling at runtime with help of 80# the ifconfig(8) utility, and select the CPU fraction reserved to 81# userland with the sysctl variable kern.polling.user_frac 82# (default 50, range 0..100). 83# 84# Not all device drivers support this mode of operation at the time of 85# this writing.
