Pushed to 10, 11, master. It's interesting that I could see a further ~12% speedup by using VM page-size stride on that 8 socket machine, but that's something to look at another day. The PG_CACHE_LINE_SIZE padding change gets us back to approximately where we were in 9.6. /me . o O ( Gee, it'd be really nice to see this change on a graph on a web page that tracks a suite of tests on a farm of interesting machines on each branch over time. ) -- Thomas Munro http://www.enterprisedb.com
