+# 6.10. listen-backlog
+# =====================
+#
+# Specifies:
+#
+# Connection queue length requested from the operating system.
+#
+# Type of value:
+#
+# Number.
+#
+# Default value:
+#
+# 128
+#
+# Effect if unset:
+#
+# A connection queue length of 128 is requested from the
+# operating system.
+#
+# Notes:
+#
+# Under high load incoming connection may queue up before
+# Privoxy gets around to serve them. The queue length is
+# limitted by the operating system. Once the queue is full,
+# additional connections are dropped before Privoxy can accept
+# and serve them.
+#
+# Increasing the queue length allows Privoxy to accept more
+# incomming connections that arrive roughly at the same time.
+#
+# Note that Privoxy can only request a certain queue length,
+# whether or not the requested length is actually used depends
+# on the operating system which may use a different length
+# instead.
+#
+# On many operating systems a limit of -1 can be specified to
+# instruct the operating system to use the maximum queue length
+# allowed. Check the listen man page to see if your platform
+# allows this.
+#
+# On some platforms you can use "netstat -Lan -p tcp" to see the
+# effective queue length.
+#
+# Effectively using a value above 128 usually requires changing
+# the system configuration as well. On FreeBSD-based system the
+# limit is controlled by the kern.ipc.soacceptqueue sysctl.
+#
+# Examples:
+#
+# listen-backlog 4096
+#
+#listen-backlog -1
+#
+# 6.11. enable-accept-filter
+# ===========================
+#
+# Specifies:
+#
+# Whether or not Privoxy should use an accept filter
+#
+# Type of value:
+#
+# 0 or 1
+#
+# Default value:
+#
+# 0
+#
+# Effect if unset:
+#
+# No accept filter is enabled.
+#
+# Notes:
+#
+# Accept filters reduce the number of context switches by not
+# passing sockets for new connections to Privoxy until a
+# complete HTTP request is available.
+#
+# As a result, Privoxy can process the whole request right away
+# without having to wait for additional data first.
+#
+# For this option to work, Privoxy has to be compiled with
+# FEATURE_ACCEPT_FILTER and the operating system has to support
+# it (which may require loading a kernel module).
+#
+# Currently accept filters are only supported on FreeBSD-based
+# systems. Check the accf_http(9) man page to learn how to
+# enable the support in the operating system.
+#
+# Examples:
+#
+# enable-accept-filter 1
+#
+#enable-accept-filter 1
