Relative to 8.0, I am seeing a dramatic, almost miraculous reduction in CPU load times in 8.1devel. This is for ISAM style access patterns over the parse/bind interface. (IOW one record at a time, 90% read, 10% write). Relative to commercial dedicated ISAM storage engines, pg holds up very well except in cpu load, but 8.1 is a huge step towards addressing that. So far, except for one minor (and completely understandable) issue with bitmap issues, 8.1 has been a stellar performer. Also great is the expansion of pg_locks view (which I didn't see mentioned in Bruce's TODO list, just FYI).
