  What is the impact of using a large value (>100) for the backlog param
to listen()?  Does it impact performance?  I assume that it eats some kind
of kernel memory space, so how much?

  I know there is an old standard of a maximum of 5 for the backlog param.
But most modern systems can handle much large values.  Is there any
disadvantage to using the maximum value (I believe under FreeBSD, this is
255) all the time?

Tom
