An essential part of database performance testing is viewing the statistics generated by the database during the test and in 2009 HammerDB introduced automatic AWR snapshot generation for Oracle for the TPC-C test. you can now do that with Oracle Metrics. . The CPU option allows you to view the original live CPU metrics window.

APM solutions track key software application performance metrics using monitoring software and telemetry data. These solutions provide performance metrics for applications, with specific insights into the statistics, such as the number of transactions processed by the application or the response time to process such transactions.

An example of a flame graph can be found below: Each box is a function in the stack, and wider boxes mean more time the system was busy on CPU on these functions. An example is kubectl-flame ( [link] ). For example, if you specify the NodeJS language, it produces the flame graph based on perf output. ✔ Launching profiler.

The reason for reporting both TPM and NOPM performance metrics is for both historical and performance reasons. However as other databases were added they all record TPM in a slightly different way so it wasn’t possible to compare TPM between different database for example Oracle and SQL Server. There are 2 reasons.

"I made my pages faster, but my business and user engagement metrics didn't change. The performance plateau is the point at which changes to your website’s rendering metrics (such as Start Render and Largest Contentful Paint) cease to matter because you’ve bottomed out in terms of business and user engagement metrics.

is the refactoring of the stored procedures for some of the TPROC-C workloads. This means that the performance metrics reported in NOPM/TPM could be different from previous releases as well as the ratio between NOPM and TPM for these workloads. Firstly it is important to understand the metrics NOPM, TPM and the difference between them.
