          Run your command under "truss" and see what's taking a long time:
          truss -f -a -vall -d -l -o /path/to/output/file java -jar /sanshare/java/....
          See the man page for "truss" to see what those options do. Inside the output file, you'll see a summary of all system calls your Java process makes, and importantly in this case a timestamp for when they returned, so you can see which ones took a long time.

          The problem could be on your web server side. Is the web server trying to do a reverse DNS lookup on the IP you're connecting from?

              What does it look like it's doing there?

                hi,

                still having issues with this, and everyone i ask seems to skirt the actual issue,

                anyway managed to find out what the issue is i think, just need to know what is causing it:

                i get the following loop in my truss output this accounts for around 6 seconds of time:

                lwp_cond_wait(0x0010AE48, 0x0010AE30, 0xD6EFFD40, 0) Err £62 ETIME
                condvar type: USYNC_THREAD
                mutex type: USYNC_THREAD
                timeout: 0.049996796 sec


                can anyone tell me what the above is doing, and if i can stop it from happening?

                  Hello again,

                  still having this issue we have stood up an x86 version of Solaris 10 and it has run < 1Second however the solaris sparc version still runs in 20Secs + has anyone got any ideas why the JVM would run any slower on Solaris SPARC and has anyone got any hints on how to speed it up?

                  Many Thanks
