AC/RC is just an experimental I asked for - not sure it will help. Its an adaptive page close - so really comes down to page hits. Could be situational and worth experimenting with in 32m. There are a few asociated parameters - not sure SHam put all of those in for the hit/miss counters.


EDIT: Just to clarify - pages are held open to reduce sequential read latency. However, if you get a page miss, you've got the additional 'open page search' + page open latency added to a read (tCL (ras~cas) + any other turn around timing. The AC function closes open pages based upon hit and miss thresholds (it appears these can be adjusted). Due to the nature of reads the latency gains are largely a game of chance.

won't really help with other benches except 32m ...dunno how much gains yet...
