Using a two-core server generating enough traffics and achived over 8000 ticks/s. mongod runs 65% CPU time.
Simple test in simulated ticks: single node process had throughput of 2394 ticks per second. mongod runs at 44% CPU usage.
Spent a few hours building a simple MongoDB cluster with Digital Ocean VPS. Three nodes: Primary, Secondary and Arbiter. Primary node is located in New York and Secondary node is in San Francisco. Arbiter is also in New York leveraging … Continue reading
