Leveraging pgbench , which is a benchmarking utility that comes bundled with PostgreSQL, I will put the cluster through its paces by executing a series of DML operations. And now, execute the benchmark: -- execute the following on the coordinator node pgbench -c 20 -j 3 -T 60 -P 3 pgbench The results are not pretty.

This includes metrics such as query execution time, the number of queries executed per second, and the utilization of query cache and adaptive hash index. Replication lag can occur due to various factors such as network latency, system resource limitations, complex transactions, or heavy write loads on the primary/master database.

All of the SPECfp_rate2000 results were downloaded from www.spec.org, the results were sorted by processor type, and “peak floating-point operations per cycle” was manually added for each processor type. Building separate models for each of the benchmarks was required to get the correct asymptotic properties.

Site performance is potentially the most important metric. Google’s industry benchmarks from 2018 also provide a striking breakdown of how each second of loading affects bounce rates. seconds faster on average and it drove 60 million more Firefox downloads per year. billion if the site slowed down by just one second.

The scale of the effect can be deeply situational or hard to suss out without solid metrics. Since then, the metrics conversation has moved forward significantly, culminating in Core Web Vitals , reported via the Chrome User Experience Report to reflect the real-world experiences of users. Today, either method returns a similar answer.
