The drawback is a moderate (up to 1/HZ seconds) 63# potential increase in response times. 64# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING 65# to achieve smoother behaviour. 66# Additionally, you can enable/disable polling at runtime with help of 67# the ifconfig(8) utility, and select the CPU fraction reserved to 68# userland with the sysctl variable kern.polling.user_frac 69# (default 50, range 0..100). 70# 71# Not all device drivers support this mode of operation at the time of 72# this writing.
