What type of data is written into the server-side "log_performance"-log, which is written in addition to the normal "log_eclntjsfserver"-log? How can I interpret?
Baiscally the performance-logging is quite useful when analyzing situations in which users report slow response times. You can find information that tells if it is the network side (e.g. slow traffice), the server-prcoessing side (e.g. actionListener) ot the client side (e.g. dynamically created form which is verrrry big).
