I'm glad to hear I steered you in the right direction!  Just remember 
to use FTP in the future any time you want to check network performance.

Not having touched Solaris or a Sparc based system in almost 5 years, I 
cannot really comment on these settings in your /etc/system file. What 
I see on the Sun web site indicates this sets the size (in entries) of 
the TCP connection hash table, with the default value being 512.  One 
would think this would affect TCP connections for both reading and 
writing equally.  But then again..... I don't really know!  The Sun 
docs do say only to change it from the default if you expect to 
consistently have more than a few thousand concurrent TCP connections.

Anyway, I'm glad to have been of service....
