FOP scalability

2002-04-19 Thread Zahigian, Mike
Does anyone know how efficient FOP might be when running on Sun Solaris box? If I am using XSL template objects to optimize performance, how might response times vary with increased number of users? Assume the Solaris box is a single 420R with 4 cpus and 4GB of RAM. Any help is this regard and id

You could have additional servers (can be low-cost) and use JMS to post jobs to a queue. These additional servers will listen on the queue (automatic load-balancing through use of JMS), generate PDFs and send a message back that the file is ready to be taken by the front servlet. > I have FOP 0.20

I've never really done this for real, but I think I'd do it like this: On the first HTTP-Request, the job gets sent on the JMS queue. The user receives a "Please wait.." page with an automatic refresh and and ID that will be returned to the server upon refresh. Use the ID in a message selector to

I'm working on this problem as we speak. I'm experimenting with wrapping the FOP engine in a stateless session bean so I can limit the number of max-free-beans in the pool. (I'm using Weblogic, I'm not sure what facilities other app servers have for clustering/pooling stateless session beans.) Anot
