Thanks for helping out. I'm accessing Tomcat directly. The 3 servers on which the problem occurs have different network cards and also differnet from the NIC on the one workstation where everything works fine. The hardware is all fairly recent. I didn't do any packet analysis. I'll get Ethereal and tinker with it. Never done that before...
Here's an interesting thing. I tried Jetty on the same boxes and uploads go at full network speed. -- Mike ----- Original Message ----- From: "Parsons Technical Services" <[EMAIL PROTECTED]> To: "Tomcat Users List" <[email protected]> Sent: Tuesday, February 01, 2005 2:42 PM Subject: Re: Slow HTTP upload of POST content > Well for the life of me I can't find it either.
