We've been load testing an application that will be allowing customers to enter their email information through the web. The loadrunner application was experiencing periodic freezing after which it would go back to normal. Reviewing the statspack information I saw a high number of buffer busy waits with the majority of the buffer waits being data block waits. This is not surprising, since the application is doing heavy inserts into several tables.
The recommendation from an article I have is to create multiple freelists for the tables undergoing heavy inserts. I've never done this before and I have no idea of how many to create. Increase the freelists from 1 to 2? More? What about freelist groups?

And am I correct that the table must be dropped and recreated to increase this parameter?

I was hoping to have read Gaja's book before I had to deal with this but it's still in the mail :).

Thanks in advance.
