How is your client connecting to the JBoss server? RMI-IIOP? SOAP? XML-RPC? How many connections are you dealing with -- 10,000 connections per second, or 2 per 5 seconds? What kind of data is being transmitted -- big/small? How much faster is the Windows server? (ie - The Linux server takes 10 seconds to do the same remote operation that takes 5 on Windows). I'm assuming that you're working on 64-bit hardware (Opteron?). Is this correct? Are you running IPv6? What is the output of these commands (run as root): uname -r sysctl net.ipv4.tcp_tw_recycle sysctl net.ipv4.tcp_keepalive_intvl sysctl net.ipv4.tcp_fin_timeout -Bryan /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
