What version of Solaris are you running? The connection fudge factor may be scaling out of control for you.

Performance addressing: Threading will add some performance problems since it's constantly opening and closing the fd. Blocking is the correct way to address threaded writes to a fd (since it will wait for all oddities of tcp)- In comparing a read / write test of 1024 bytes in Stevens' UNIX Network Programming (1998), you see how an un blocked, non threaded program took 8.8 seconds to transfer, while a non threaded version with out blocking, did the same xfer in .3 seconds. Hardware in place were all 100 fe switches.

That book is an excellent resource for performance issues that are difficult to spot.

redsocks

REDSOCKS(8)						      System Manager's Manual						       REDSOCKS(8)

NAME

       redsocks - rediect any TCP connection to a SOCKS or HTTP proxy

SYNOPSIS

       redsocks [options]

DESCRIPTION

       redsocks  is  a	daemon	running on the local system, that will transparently tunnel any TCP connection via a remote SOCKS4, SOCKS5 or HTTP
       proxy server. It uses the system firewall's redirection facility to intercept TCP connections, thus the redirection  is	system-wide,  with
       fine-grained control, and does not depend on LD_PRELOAD libraries.

       Redsocks supports tunneling TCP connections and UDP packets. It has authentication support for both, SOCKS and HTTP proxies.

       Also included is a small DNS server returning answers with the "truncated" flag set for any UDP query, forcing the resolver to use TCP.

OPTIONS

       -p pidfile
	      Write the process ID to pidfile.

       -c config
	      Use config as configuration file.

       -t     Test configuration file syntax.

SEE ALSO

       iptables(8), /etc/redsocks.conf
