Brett, I have a similar problem. But what is interesting is that it only seem slow when I test using a Windows 2000 pro box using IE 6 against a Windows 2003 Server. Try using an XP pro box to test the same functionality.
Also, here are diagrams that explain the situation I am having. I have submitted the issue to Microsoft and have one of their engineers on the case. I will keep everyone posted on what they discover. (please view this email in plain text for diagrams to display correctly below) File Download from ONE is slow, ALL others are FAST Windows 2003 Server: Windows 2000 Professional |-----------------------| |-----------| | Tomcat 5.0.28 | SLOW | | | IIS6 |-------------> | IE6 | | JK2 | FROM CART | | |-----------------------| |-----------| Windows 2003 Server: Windows 2000 Professional |-----------------------| |-----------| | Tomcat 5.0.28 | FAST | ANY OTHER | | IIS6 |-------------> | BROWSER | | JK2 | FROM CART | | |-----------------------| |-----------| Windows 2003 Server: Windows XP and Mac OSX |-----------------------| |-----------| | Tomcat 5.0.28 | FAST | IE 6 | | IIS6 |-------------> | or Safari | | JK2 | FROM CART | | |-----------------------| |-----------| Windows 2003 Server: ALL recent OS's |-----------------------| |-----------| | Tomcat 5.0.28 | FAST | All recent| | (running on |-------------> | browsers | | port 8080 standalone) | FROM CART | | |-----------------------| |-----------| RedHat Linux ALL recent OS's |-----------------------| |-----------| | Tomcat 5.0.28 | FAST | All recent| | Apache 2.0.x |-------------> | browsers | | JK2 | FROM CART | | |-----------------------| |-----------| Downloading a 1.3M file from a website cart to a Windows 2000 Pro desktop running latest IE 6 is slow and takes 15 seconds Downloading the same 1.3M file to a Windows XP box running IE 6, a Windows Pro box running Mozilla, and a Mac OSX running safari takes approx 1 second Spoke with Microsoft, we put a 1M file in a virtual directory on IIS. It downloaded in approx 1 second to Windows Pro / IE6. When I take IIS/mod_jk out of the picture, and go directly to Tomcat on 8080 the download is fast to All OS's and Browsers. Also, Apache has no problem downloading the file fast to All OS / browser combinations, including Windows 2000 / IE6!!! So does anyone know why the download is slow between IIS 6 and Windows 2000 Pro / IE6 and fast to all other clients. Is there something I can do to my IIS server to make the download go faster. Two other facts that are important... 1. the file being downloaded from the cart is on a remote file server and is being published through IIS via a UNC path from a shared folder. This is true for all scenarios shown above. And, 2. We are required to run IIS 6 in IIS 5 isolation mode due to the isapi_redirector2.dll can not handle IIS 6 native mode under large loads. I did try to do the download running IIS 6 in native mode, but the download was still slow. Seems to be a weird buffer restriction when IIS 6 and IE6 on Windows 2000 talk to each other. Confounded. Any suggestions???? -----Original Message----- From: Brett Parsons [mailto:[EMAIL PROTECTED] Sent: Thursday, November 04, 2004 1:45 PM To: [EMAIL PROTECTED] Subject: Tomcat JK2 Connector/IIS Slowdown Hi Everyone, I'm having some JSP performance problems using the JK2 Connector between Tomcat 5 and IIS6 in Windows Server 2003. If I hit my site as "mySite:8080", everything works fine. However, if i just hit "mySite", thus going through the JK2 connector, the performance of the JSP pages greatly decreases (load times are about 4-5 times greater). Even stranger is that this slowdown occurs only on some computers and not others. I have already tried setting the "enableLookups=false" attribute in the server.xml file, but this does not have any effect. Can someone recommend other steps I can follow to improve the performance of my JSP pages when going through the JK2 connector?
