Summary: IIS JK can't handle request under heavy load
Product: Tomcat 5
Version: Unknown
Platform: Other
OS/Version: other
Status: NEW
Severity: normal
Priority: P2
Component: Native:JK
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: gunsnroz@hotmail.com
Using isapi_redirect.dll under IIS,
I found that HTTP request is not handled (looks like hang).
My enviroment is :
* Web server
- Windows 2000 SP4
- IIS 5.0
- isapi_redirect.dll (1.2.8 or above)
* Servlet
- Fedora core 3
- Tomcat 5.0.28
I used the Microsoft Stress Tool with these settings:
----------------------
GET /servlet-examples/servlet/RequestInfoExample (delay 10)
Concurrent Connection : 30
Test Run time : 1 min.
-----------------------
When I run the MS Stress tool, the first 10 ~ 30 requests are handled.
(verified by tomcat's access log) but all the remaing requests are not processed
and the result codes are all '403 forbidden'.
When I use web browser, the IIS shows '403 too many connection' or something
like that.
I'll attach the test result of MS stress tool.
Using isapi_redirect 1.2.6, I get the better result (few 403 error ratio about
1/10).
