From a user experience ....
# Make sure you're on the latest version of 11G (5188). They make performance improvements with every release.
# configure jdeveloper to open jsp/jsff's in source view.
# Use the property editor if possible. Avoid typing in the source
# Disable the source control plugin - Use Tortoise SVN or other source control outside of jdeveloper.
# Recommend a minimum of 3G but 4G preferred
# set the ide.conf memory size to at least 768
# Restart jdeveloper if memory usage climbs above 1G
Do you any tips? or more explanations to this?
