Interesting - we just got an OutOfMemoryException and sluggish
performance in our application when we were rendering 4000+ Data rows
in a datatable.
Just a heads-up, do NOT use SiteMesh in it's current state if you are going to return very large pages that have to be decorated. I switched from using Tiles to Sitemesh and overall I really like Sitemesh, but I had to chuck it out since there is the potential for very large pages to cause out of memory issues. The problem is the whole output is stored in a buffer before it's decorated and then flushed. Storing a huge amount of data in even a StringBuffer could cause a problem if you don't have a lot of RAM.
