Hi Sean >I've been working on trying to improve performance of our >busiest tables by tuning freelists. The results are not = earth-shattering, >however, and wondered if I could get some feedback from the list. Eventually the results are not earth-shattering because freelists are = not the main problem (i.e. the real bottleneck). Why do you think they = are?=20 In addition if you carefully tune the number of freelists and freelists = groups, they are not that bad. Chris -- //www.freelists.org/webpage/oracle-l
