Sorry to repost this, but I just lost all of my email from the past two days. Arghh!

I have a table that is ~100Mb in size. The table will always contain 500,000 to 1,000,000 records in it at any given time and approximately that number of inserts, updates and deletes will be performed against it on a daily basis. Only one user will be performing the DML operations on the table and that will be via a background process (i.e. daemon).

The table has no foreign keys nor a primary key but it may require an index or two because of the updates and deletes. Unfortunately, I can't put the table on a dedicated disk and I am stuck with Raid-5.

My question is, what suggestions does anyone have to offer that will give me the best possible I/O in this case? Is trying to put this table in a Keep pool going to help at all?

Thanks again for your advise (and patience).
