Description
===========

Options
=======

.. program:: traffic_server

.. option:: -n COUNT, --net_threads COUNT

.. option:: -Z COUNT, --cluster_threads COUNT

.. option:: -U COUNT, --udp_threads COUNT

.. option:: -a, --accepts_thread

.. option:: -b, --accept_till_done

.. option:: -p PORT, --httpport PORT

.. option:: -P PORT, --cluster_port PORT

.. option:: -f, --disable_freelist

In order to improve performance, :program:`traffic_server` caches
commonly used data structures in a set of free object lists. This
option disables these caches, causing :program:`traffic_server` to
use :manpage:`malloc(3)` for every allocation. Though this option
should not commonly be needed, it may be beneficial in memory-constrained
environments or where the working set is highly variable.

.. option:: -o LEVEL, --dprintf_level LEVEL

.. option:: -R LEVEL, --regression LEVEL

.. option:: -r TEST, --regression_test TEST

.. option:: -l, --regression_list

If Traffic Server was built with tests enabled, this option lists
the available tests.

.. option:: -T TAGS, --debug_tags TAGS

.. option:: -B TAGS, --action_tags TAGS

.. option:: -i COUNT, --interval COUNT

.. option:: -M, --remote_management

.. option:: -C CMD, --command CMD

.. option:: -k, --clear_hostdb

.. option:: -K, --clear_cache

.. option:: -c CORE, --read_core CORE

.. option:: --accept_mss MSS

.. option:: -t MSECS, --poll_timeout MSECS

.. option:: -h, --help

   Print usage information and exit.

.. option:: -V, --version

   Print version information and exit.
