All of the performance tests reported here were run by executing the lwreg commands on a two-year old workstation with a 3.8 GHz Intel Xeon W-1270P CPU and 64 GB of RAM running Ubuntu 22.04. The database was a PostgresSQL v14 installation running on an eight-year old workstation with a 3.5GHz Intel Xeon E3-1240 CPU and 32GB of RAM running Ubuntu 22.04. The default Ubuntu PostgreSQL configuration was used without further performance tuning.
