# NETWORKING OPTIONS
|

|

#
|
||
# DEVICE_POLLING adds support for mixed interrupt-polling handling
|
||
# of network device drivers, which has significant benefits in terms
|
||
# of robustness to overloads and responsivity, as well as permitting
|
||
# accurate scheduling of the CPU time between kernel network processing
|
||
# and other activities. The drawback is a moderate (up to 1/HZ seconds)
|
||
# potential increase in response times.
|
||
# It is strongly recommended to use HZ=1000 or 2000 with DEVICE_POLLING
|
||
# to achieve smoother behaviour.
|
||
# Additionally, you can enable/disable polling at runtime with the
|
||
# sysctl variable kern.polling.enable (defaults off), and select
|
||
# the CPU fraction reserved to userland with the sysctl variable
|
||
# kern.polling.user_frac (default 50, range 0..100).
