I think that you will have an update to the sequence number EVERY time instead of every 20 times. That's mean I/o for every nextval.

CACHE 20 is the default, so if you remove the clause, it will have absolutely no impact on performance or anything else...

...of course, I get the feeling that that wasn't the gist of your question, was it?

I have been given create scripts for sequences to be used in tables that will be loaded via bulk loads. How huge is the potential performance hit if I take out the cache 20?
