# low latency is important so we highly recommend that you disable hyper
# threading on Intel CPUs as it has an unpredictable affect on latency, cpu
# cache misses and load.
#
# These settings are specifically tuned for a "low" latency FIOS (300/300) and
# gigabit LAN connections. If you have 10gig or 40gig you will need to increase
# the network buffers as proposed. "man tuning" for more information.
