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?

GHz 4th Generation Intel Xeon Scalable processors (code-named Sapphire Rapids) Up to 20% higher compute performance than z1d instances Up to 50 Gbps of networking speed Up to 40 Gbps of bandwidth to the Amazon Elastic Block Store (EBS) We can also verify these capabilities by running some simple benchmarks on the different subsystems.

The idea behind this is to speed up cluster resources such as garbage collection, reduce image transfer over the network, and accelerate the application launch. MySQL is not written in NodeJS, but we specify –lang node to launch the perf profiler, which is compatible with C/C++.

Yet, we wanted to put together our list of the top web performance books for anyone who cares about speed of the web and would like to explore the timeline of web performance engineering milestones over nearly two decades through the lens of published books. Site speed & SEO go hand in hand. Web Performance Tuning.

As (C) looked like a kernel rebuild, I started with (D) and (E). ## 5. Measuring the speed of time Is there already a microbenchmark for os::javaTimeMillis()? I also rewrote this in C and called gettimeofday(2) directly: $ cat gettimeofdaybench.c. Microbenchmark os::javaTimeMillis() on both systems. include <sys/time.h>

Some opinions claim that “Benchmarks are meaningless”, “benchmarks are irrelevant” or “benchmarks are nothing like your real applications” However for others “Benchmarks matter,” as they “account for the processing architecture and speed, memory, storage subsystems and the database engine.”
