Hi,
I am wondering if anybody can provide any inputs regarding IHS-WAS 3.5.5 performance.
Currently, links within the application are very slow - these links just load simple JSP pages.
Adjusting parameters - heap size, number of connections at various levels, and threads per child - has yielded positive results, but things still remain much slower than desired.
I'm wondering if anybody has any ideas as to what are some areas I should look at.
Right now I am looking into servletcache.xml and dynacache.xml - Does anybody have any inputs into the effectivness of these files for increasing performance?
Any inputs are appreciated.

Have not done any complex customization.
There is a file called log4j_conf.properties where you can provide your own configuration parameters.
When you are logging be sure to pay attention to the different levels of logging ie. debug, info, error etc. as you can turn these on and off inside the properties file w/o actually deleting the log statement from the code.
It comes in handy when you take the code into a production environment.

Am currently using log4j. The initial configuration and setup is not too complicated and once in place it is a very good product for debugging and logging in general.
No complaints.
If I could get the file over to the web server I could let IHS serve the file. Unfortunately, there are firewalls and other security issues which make this somewhat infeasible.
It would be nice if the File Serving Servlet had some configuration parameters which allowed it to handle such scenarios.
What if I had a web application which dynamically generated html files. How could I use WAS, IHS and OSE to show these files to the end user without placing all static content on the app server?

Hi,
I am using Websphere 3.5 for a web application.
In my application I generate PDF files dynamically on the application server and display them to the user. In order to display these PDF files to the user I enable the File Serving Servlet.
The problem is that once I enable the File Serving Servlet I need to place all my static content(gif, html, css) on the application server. I am unable to be "picky" about where I put my static content. I believe this is causing some performance degradation.
Any help is appreciated.
