Are these large uploads? Do you see a higher CPU load at this time? Could it be running out of memory? Memory starvation could cause the app to spend a lot of time garbage collecting. You can try adding -Xmx256m to the Additional Arguments in JavaMonitor to see if that helps. I don't know of any buffer/chunk size tuning parameters. I'd probably have to see the code in use.
