+ Notes:
+
+
+ Under high load incoming connection may queue up before Privoxy
+ gets around to serve them. The queue length is limited 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
+ incoming 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.
+

+
+
+ 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).

+
+ Type of value:
+
+
+ Size in bytes
+
+
+
+
+ Default value:
+
+ 5000
+
+
+
+ Notes:
+
+
+ Increasing the receive-buffer-size increases Privoxy's memory usage but
+ can lower the number of context switches and thereby reduce the
+ cpu usage and potentially increase the throughput.
+
+
+ This is mostly relevant for fast network connections and
+ large downloads that don't require filtering.
+
+
+ Reducing the buffer size reduces the amount of memory Privoxy
+ needs to handle the request but increases the number of systemcalls
+ and may reduce the throughput.
+
+
+ A dtrace command like:
+ sudo dtrace -n 'syscall::read:return /execname == "privoxy"/ { @[execname] = llquantize(arg0, 10, 0, 5, 20); @m = max(arg0)}'
+ can be used to properly tune the receive-buffer-size.
+ On systems without dtrace, strace or truss may be used as
+ less convenient alternatives.
+
+
+ If the buffer is too large it will increase Privoxy's memory
+ footprint without any benefit. As the memory is (currently)
+ cleared before using it, a buffer that is too large can
+ actually reduce the throughput.
