TCP stack throughput

So this means 500 simultanous connection requests on Solaris and  
about 300 on Mac OSX (FreeBSD). My question, I suppose, is whether  
this is high enough.

Is there a limitation in Erlang or is this maxing out the platform  
TCP stack?

What do you folks recon?

     Thanks, Joel
