This has performance results for Postgres 18 beta1 and several older Postgres releases using the sysbench benchmark and a small server. Results like this from me are usually boring because Postgreshas done a great job at avoiding performance regressions over time. This work was done by Small Datum LLC and not sponsored.tl;dr – from Postgres 17.5 to 18 beta1there might be small regressions (1% to 4%) in a few range query microbenchmarksthere might be a few small improvements (… Read more

Context This is why you need to learn MySQL query response time: Performance is query response time. This book explores that idea from various angles with a single intent: to help you achieve remarkable MySQL performance. Efficient MySQL performance means focusing on the best practices and techniques that directly affect MySQL performance—no superfluous details or deep internals required by DBAs and experts. I presume that you’re a busy professional who is using MySQL, not managing it, and that you need the most results for the least effort. That’s not laziness, that’s efficiency. To that end, this book is direct and… Read more
