In addition to this: Cocoon *requires* tuning in order to make it work fast. Search for "performance", "tuning" in the users and developers email archives, it was discussed couple of times but not documented. PS: Tuning could be for: memory, high concurrent users load, startup time, etc. Vadim --------------------------------------------------------------------- Please check that your question has not already been answered in the FAQ before posting. <http://xml.apache.org/cocoon/faqs.html> To unsubscribe, e-mail: <[EMAIL PROTECTED]> For additional commands, e-mail: <[EMAIL PROTECTED]>
