As developers, we rightfully obsess about the customer experience, relentlessly working to squeeze every millisecond out of the critical rendering path, optimize input latency, and eliminate jank. Surveying the existing landscape of available developer tools and runtimes, we felt that there is a gap. Stay tuned for more in 2022!

This post complements the previous best practice guides this time with the focus on MySQL and MariaDB and achieving top levels of performance with the HammerDB MySQL TPC-C test. System setup is covered on the PostgreSQL Best Practice post so it will not be repeated here as the steps are the same. innodb_file_per_table.

Learnings and emerging best practices. The success of ML-centric projects depends heavily on data availability, quality, and management. ML-centric software also sees frequent revisions initiated by model changes, parameter tuning, and data updates, the combination of which can have a significant impact on system performance.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Checking those available: $ cat /sys/devices/system/clocksource/clocksource0/available_clocksource. I've shared many posts about superpower observability tools, but often humble hacking is just as effective.

Data Pipeline A data pipeline is a software that ingests data from multiple sources, transforms it and finally makes it available to internal or external products. In certain scenarios exactly-once semantics is possible but the best you can do is at-least-once or at-most-once. Generally speaking, data pipelines are leaky by nature.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. The change was obvious in the production graphs, showing a drop in write latencies: Once tested more broadly, it showed the write latencies dropped by 43%, delivering slightly better performance than on CentOS.

Because we are dealing with network protocols here, we will mainly look at network aspects, of which two are most important: latency and bandwidth. Latency can be roughly defined as the time it takes to send a packet from point A (say, the client) to point B (the server). Two-way latency is often called round-trip time (RTT).

You would, however, be hard-pressed even today to find a good article that details the nuanced best practices. This is because, as I stated in the introduction to part 1 , much of the early HTTP/2 content was overly optimistic about how well it would work in practice, and some of it, quite frankly, had major mistakes and bad advice.

You’ve probably heard things like: “HTTP/3 is much faster than HTTP/2 when there is packet loss”, or “HTTP/3 connections have less latency and take less time to set up”, and probably “HTTP/3 can send data more quickly and can send more resources in parallel”. Stay tuned! (vf, QUIC has a higher encryption overhead. vf, il, al).
