Web pages are unbelievably complex, and there are hundreds of different metrics available to track. A performance budget is a threshold that you apply to the metrics you care about the most. This is when you run into three important questions: Which metrics should you focus on? Which metrics should you focus on?

In 2019 our stunning colleagues in the Cloud Database Engineering (CDE) team benchmarked EBS performance for our use case and migrated existing clusters to use EBS Elastic volumes. Build abstractions that correlate data from metrics, logging, and tracing systems to provide additional contextual information for troubleshooting.

Here are some common questions I’m asked when I talk with people about performance: Which metrics should I care about? What types of devices and connections should I test on? What are some good sites I can use for benchmarking? Identify sites you can use for your own competitive benchmarking. How fast should I be?

For example HammerDB has not used tpmC terminology to report TPC-C based metrics instead using TPM and NOPM nomenclature. The HammerDB TPROC-C workload by design intended as CPU and memory intensive workload derived from TPC-C – so that we get to benchmark at maximum CPU performance at a much smaller database footprint.

SpeedCurve focuses on a third which I like to call web performance benchmarking. It's often called synthetic testing as tests are run from servers in a data centre and don't accurately represent what speeds an actual user might get. Web Performance Benchmarking. Uptime Monitoring. Real User Monitoring.

HammerDB is a software application for database benchmarking. Databases are highly sophisticated software, and to design and run a fair benchmark workload is a complex undertaking. The Transaction Processing Performance Council (TPC) was founded to bring standards to database benchmarking, and the history of the TPC can be found here.

HammerDB doesn’t publish competitive database benchmarks, instead we always encourage people to be better informed by running their own.

To show that I can criticize my own work as well, here I show that sustained memory bandwidth (using an approximation to the STREAM Benchmark ) is also inadequate as a single figure of metric. (It Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

Tracing as a foundation Logs, metrics, and traces are the three pillars of observability. Metrics communicate what’s happening on a macro scale, traces illustrate the ecosystem of an isolated request, and the logs provide a detail-rich snapshot into what happened within a service. The downside is that we have so many dashboards.

Running speed tests with tools like Google PageSpeed Insights , WebPageTest , or KeyCDN’s Website Speed Test are always a good way to help gauge your website’s performance. While these metrics can be very helpful it is also important to keep this data in perspective.

Improving latency and reducing variance allows teams to test other product hypotheses with less noise. Teams I've consulted are too often wrenched between celebration over "the big rewrite" launch and the morning-after realisation that the new stack is tanking business metrics.
