Hardware Memory The amount of RAM to be provisioned for database servers can vary greatly depending on the size of the database and the specific requirements of the company. Operating system Linux is the most common operating system for high-performance MySQL servers. I hope this helps!

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.

Out of the box, the default PostgreSQL configuration is not tuned for any particular workload. It is primarily the responsibility of the database administrator or developer to tune PostgreSQL according to their system’s workload. What is PostgreSQL performance tuning? Why is PostgreSQL performance tuning important?

Are there inherent time relationships in the messages that need to be preserved as they travel across the system? The data shape will dictate capacity planning, tuning of the backbone, and scalability analysis for individual components. What message process warranty level do we require? At least once? At most once? Exactly once?

Because recognizing if the workload is read intensive or write intensive will impact your hardware choices, database configuration as well as what techniques you can apply for performance optimization and scalability. Let’s now look at the operating system level. Why should you care? Not all writes are equal either.

For this reason we need to implement our database sessions in the form of operating system threads. This is possible because the Tcl interpreter is exceptionally compact and lightweight (Also for this reason Tcl is often used as an embedded language in hardware such as Cisco Routers).

Prior to SQL Server 2012, the maximum server memory value only applied to the bufferpool, so customers needed to limit the amount of memory the bufferpool could use to save memory for the operating system and other processes. If you have big physical hardware with defaults, then you should look at optimizing MAXDOP.

Not all back-end errors affect the user experience, but keeping track of them can prove helpful when tuning your app. Monitoring errors on the front-end requires a bit more work because front-end performance is highly dependant on the user’s hardware, software and connection.
