When we do benchmarks, it's important that we measure best practices, and typical usage. Benchmarking anti patterns and stored procedures tells us nothing about the development model we typically see out there as we actually start using the thing. Watch me run you through the code below.

This is the first time I have benchmarked it with a realistic example. I have generally held the view that replicating data to a secondary system is faster than sync-ing to disk, assuming the round trip network delay wasn’t high due to quality networks and co-located redundant servers. Little’s Law and Why Latency Matters.

The Linux VM running postgres has two virtual disks – one taking transaction log writes. These low-concurrency log writes also hit oplog.

In a previous article, we looked at How to compare strings in Go and did some benchmarking. Comparing two strings to see if they’re equal takes processing power, but not all comparisons are the same. We’re going to expand on that here. It may seem like a small thing, but as all great optimizers know, it’s the little things that add up.

Most metrics are not atomic: FCP, for example, isn’t a metric we can optimise in isolation—it’s a culmination of other more atomic metrics such as connection overhead, TTFB, and more. For the sake of ease, I’m going to use Largest Contentful Paint (LCP) as the example. For example, continuing our task to reduce CSS size: performance.

Synthesizing data structure transformations from input-output examples , Feser et al., Program synthesis from examples falls into that latter camp, and the use case addressed here is a perfect fit for it: transforming data structures.
