Kevin Grittner 2201d801b0 Avoid extra locks in GetSnapshotData if old_snapshot_threshold < 0 ... On a big NUMA machine with 1000 connections in saturation load there was a performance regression due to spinlock contention, for acquiring values which were never used. Just fill with dummy values if we're not going to use them. This patch has not been benchmarked yet on a big NUMA machine, but it seems like a good idea on general principle, and it seemed to prevent an apparent 2.2% regression on a single-socket i7 box running 200 connections at saturation load.		2016-04-12 11:48:02 -05:00
