Back in 2014, I wrote an article called Performance Tuning the Whole Query Plan. The optimizer chooses this plan without any hints on my system configuration because the estimated cost of the plan is below the cost threshold for parallelism. Performance is competitive at around 15ms. BountyAmount ; Performance Summary Table.

I was a bit perplexed by this issue, since the system was certainly no slouch — plenty of cores, 3TB of memory, and XtremIO storage. If you have instances running older versions like SQL Server 2008 R2 (I found one!), writes/sec average throughput: 46.96
