Traditional computing models rely on virtual or physical machines, where each instance includes a complete operating system, CPU cycles, and memory. There is no need to plan for extra resources, update operating systems, or install frameworks. The provider is essentially your system administrator.

For optimum performance, a PostgreSQL database depends on the operating system parameters being defined correctly. Poorly configured OS kernel parameters can cause degradation in database server performance. PostgreSQL uses System V (SysV) that requires SHMMAX setting. This results in improved performance.

But for this to be realized in a practical manner, the system has to (1) be able to accurately control its aggressiveness to minimize the impact on application performance, and (2) be resilient to the variation of cold memory behavior across different machines,clusters, and jobs. Enter zswap!

What I find is very similar to backups: No DBCC CHECKDBs performed at all DBCC CHECKDBs being performed only on select databases DBCC CHECKDBs last performed months or years ago. Performing index maintenance by removing fragmentation from your indexes is still important. Index Maintenance.

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. If you only test your own application (and if you have more than one application which one will you use for benchmarking?)

For e.g., if accessing file system over WebDAV or FTP has performance issues, and it will take 4 hours to fix, then for those 4 hours, you can just kill FTP/WebDAV at kong/firewall and ask customers to use web UI or other mechanisms to work. Who performs what roles? What operating systems do you use?
