Their diagrams show `Request per seconds'. What should that mean? How many connections PG accepted per second? So they measured the OS fork performance? Should that value be of any interrest? Anyone with heavy OLTP workload will use persistent connections or a connection pool in front. Do they mean TPS? That woulnd't make much sense in a CPU benchmark, as OLTP workload is typically limited by the disc subsystem. Can someone enlighten me what this site is about? -- Regards, Hannes Dorbath
