For optimum performance, a PostgreSQL database depends on the operating system parameters being defined correctly. In this post, we will discuss some important kernel parameters that can affect database server performance and how these should be tuned. PostgreSQL uses System V (SysV) that requires SHMMAX setting.

For most high-end processors these values have remained in the range of 75% to 85% of the peak DRAM bandwidth of the system over the past 15-20 years — an amazing accomplishment given the increase in core count (with its associated cache coherence issues), number of DRAM channels, and ever-increasing pipelining of the DRAMs themselves.

” This paper describes a “far memory” system that has been in production deployment at Google since 2016. Using zswap means that no new hardware solutions are required, enabling rapid deployment across clusters. The system also collects per-job cold-page histograms for a given set of predefined cold age thresholds.

On high-performance multi-core systems all the supported databases can return performance in the many millions of transactions per minute. For this reason we need to implement our database sessions in the form of operating system threads. To prevent the roundtrip between the client and database becoming the bottleneck.

As the chart shows because we know that both HammerDB and the implementation of the TPC-C workload scales then we can determine that with this particular database engine both the software and hardware scales as well.
