NDB Cluster Configuration Files Restart Type N (NDB 8.0.13) Version (or later) NDB 8.0.13 Type or units integer Default 5 Range 0 - 10 Restart Type N (NDB 8.0.13) This parameter specifies the time in microseconds for threads to be executed in the scheduler before being sent. Setting it to 0 minimizes the response time; to achieve higher throughput, you can increase the value at the expense of longer response times. The default is 50  μ sec, which our testing shows to increase throughput slightly in high-load cases without materially delaying requests. Set the balance in the  NDB  scheduler between speed and throughput. This parameter takes an integer whose value is in the range 0-10 inclusive, with 5 as the default. Higher values provide better response times relative to throughput. Lower values provide increased throughput at the expense of longer response times. This parameter specifies the time in microseconds for threads to be executed in the scheduler before sleeping. Starting with NDB 8.0.20, if  SpinMethod  is set, any setting for this parameter is ignored.
