Another Glassfish Gotcha!
Logs again folks.
We had a big system we deployed, got 23 users in it ran like a DOG, updated Glassfish 2.1.1 still ran like a dog (but didn’t crash with permgen problems).
What was happening was simple the web stack was writing hundreds of INFO statements about combos and drop downs. I set all the logs to only report SEVERE errors and it all sped up!
