Can anyone confirm this behavior for me? The slow downloads occur if I just try to download a file through my web browser. I just want to make sure it is not something I am doing wrong. I am running Windows Server 2003 Standard Edition. I am running IIS 6.0 ,Tomcat 5.0.19, and JK2.0.4. I just put a large ZIP (30MB) file on a website a running on Tomcat and then tried downloading it. If I go through IIS and JK2 it is limited to approximately 42 KB/sec. If I connect directly to tomcat on port 8080, the same download goes at about 10 MB/sec. As you can see there is a big difference. If anyone has a similar setup to mine and can test this performance, I would really appreciate it. Thanks again.

Hello All,
Here is a image to show how it behaves on file downloads. However, when I upload a file there is no issue, it uses as much of the bandwidth as possible.

Hello,
I recently upgraded to Windows 2003 Server using IIS 6 and Tomcat 5. I have a java applet that talks to a java servlet using http. I am using IIS 6 for user authentication. Once I had it setup, I noticed that when a large amount of data was transferred from the server to the applet, it was taking much more time then it did on my older and much slower Windows 2000 server. After some experimenting I was able to see that all network traffic between the applet and servlet would max out at a consistent 0.34Mbps. Considering that the server is not doing anything else, this seems really strange since it should be capable of running at 1Gbps. When I used my old server, it could transfer a rates way above this limit. I have tried both Tomcat versions 4 and 5 and both jk and jk2 redirector. The performance is the same with any of these combinations. If I tell the applet to talk to tomcat directly on port 8080, then the performance is great. However, I need to get it to work with IIS 6. If anyone knows how this can be fixed, I would greatly appreciate it. Thanks.
