Subject Re: [jira] Commented: (GERONIMO-1674) Daytrader gets NullPointerException attempting to log in a user
Date Wed, 28 Jun 2006 16:51:02 GMT

So, at the very least the code needs to be fixed to support a smaller 
quote population.  Perhaps we could also provide 2 basic settings on the 
configuration page:

1) Default, out of box sample application (low number of users quotes)
2) Performance test,  larger default values (e.g. 1000 quotes, 500 users)

It would be good to settle on specific values for performance testing so 
results will be comparable.

Stan.
