Those redo could be because of indexes? How many indexes do you have on your 40 million row table?

I have a table with 40 million rows. Daily I load about 70,000 records into it. Each record is 128 characters wide. The flat file the data comes in is 9 megs. My redo logs are 20 megs each and I have 3 groups of them.

When I load the data, the alert log shows 29 log switches which generates a lot of archives logs. Why am I getting so many log switches? I would think that if the OS file is 9 megs and the redo logs are 20, I would at most get 1 log switch.

Thanks,
Randy
