I am running NetBSD 1.3.2 on P6 machine with en ATM interface.
When I do a ttcp test between two such machine thru an ATM switch
with OC3 connection, I get only about 4MB/s throughput in average,
which is about 32Mb/s.  

Can I get higher throughput than this?  Is that kernel overhead
cause this?

Thanks in advance
