Setting TraceMempool

If you are not satisfied with the performance of an instance of Cardano Node, then subjectively you may notice improvement in memory usage, CPU usage and/or the number of missed slot leader checks if you set the TraceMempool key to the value false in the configuration file named config.json that your Cardano Node uses.
Side effects of TraceMempool = false
  • gLiveView will show 0 for transactions processed
  • If your block producer is configured this way, troubleshooting topology / firewall / transaction processing issues may be harder to diagnose and identify. For block producer nodes, it is considered best practice to keep TraceMempool as true.
