We made the following change to reAllocBuff() in org.apache.jasper.runtime.BodyContentImpl with some success. Curious if this is of use to others. There was already a note about using a multiple of DEFAULT_BUFFER_SIZE. This takes the notion one step further, doubling size upon each request. Made a tremendous impact on performance for a page where a body tag was generating a lot of output. This function, and the array copy, were taking a big chunk of CPU to deal with the degenerate situation. Another option would be to get the bufferSize from JspWriter, as this would allow the buffer page directive to affect BodyContent as well. Felt the doubling was more effective and simple.
