      The parallel insert performance test has recently started performing better for {w:1, j:true} writes than for {w:1, j:false} in runs with high concurrency (256, 512 or 1024 threads)

      1024 threads, green j:false, pink j:true:

      512 threads, pink j:false, orange j:true

      32 threads, pink j:false, cyan j:true (j:false better as expected)
