Autoextend WAIT statistic?

Oracle says that when a file autoextends, there is a slight delay. Does anyone know which Oracle WAIT statistic that would appear under?   We have been using autoextend on OLTP production tables for awhile now, and the results have been satisfactory. This is an ERP system, so the critical performance time is at month-end. Some of the developers are concerned that table autoextending may slow batch programs, and suggesting that I should determine which tables are likely to autoextend during month-end and add storage beforehand. I would like to ensure that I am fixing a real problem (short on time, like most of you), so I am wondering if autoextend was causing a delay, what wait statistic would it show up under. Any ideas?
