Write buffers allows buffering of ongoing UDP/IP packets, providing
|
|
for higher performance, streamed output.
|
|

You might want to disable UDP/IP write buffering on a highly memory
|
|
memory constrained system where there are no performance issues.

|
|
These tiny nodes are used as "containers" to support queuing of
|
|
UDP write buffers. This setting will limit the number of UDP write
|
|
operations that can be "in-flight" at any give time. So a good
|
|
choice for this value would be the same as the maximum number of
|
|
UDP connections.

|

This option will force debug output from UDP write buffer logic,
|
|
even without network debug output. This is not normally something
|
|
that would want to do but is convenient if you are debugging the
|
|
write buffer logic and do not want to get overloaded with other
|
|
network-related debug output.

Dump the contents of the write buffers. You do not want to do this
|

unless you really want to analyze the write buffer transfers in

detail.
