Hi David,

You're probably aware of this, but just to make it explicit: Jakub
Wartak was testing performance of recovery, and one of the bottlenecks
he found in some of his cases was dynahash as used by SMgr.  It seems
quite possible that this work would benefit some of his test workloads.
He last posted about it here:

though the fraction of dynahash-from-SMgr is not as high there as in
some of other reports I saw.
