What is my UDP send/recieve buffer size

Hi,

If some one was to suggest, "increase your kernal tunables related to UDP, in particular the UDP send/recieve buffer size".... then what would they mean? Smilie

How can I find out what this current value is?

Thousand many thanks.

Neil

Posting what the OS and version is might assist in getting a correct answer!

Otherwise, look through psc.edu performance tuning guide for your OS - should at least show what the default is.
