You should use the size that corresponds to your actual workload and configuration. If you use a structure that's too small, you'll get fewer lock table entries and may encounter more false contention (when distinct resources hash to the same lock table entry) and degraded performance. If you use a structure that's too large, you'll waste some CF storage. In the case of GRS, nothing disastrous is likely to happen, and you can always adjust the size on the fly by updating the CFRM policy and rebuilding the ISGLOCK structure. CFSizer provides a starting point. It's up to you to determine what size works for your installation.
