[Beowulf] P4_SOCKBUFSIZE question

Im new to clustering.  My question is how do I determine the best

P4_SOCKBUFSIZE to use?  I have NetPipe already installed and working
to see if changing P4_SOCKBUFSIZE will work.

My cluster is 4 nodes,  kernel 2.4.22-1.2149.nptl, using 100mbit ethernet.  
Nothing too fancy, I just want to get out as much 'performance' as possible.  
Oh and what would you recommend to increase performance?  Any suggestions?

Thanks for the help,
Paul
