How does QuestDB get the kind of performance it does, and how are we continuing to squeeze another 50-60% out of it? We are constantly learning more about the fundamental concepts of memory performance, and this is one example of how what we at first thought would be worse for performance ended up bringing us a rather substantial boost in overall memory performance.

We will walk you through how some of our initial thoughts on storage and memory-mapping evolved to bring us better performance overall.

In the world of databases, benchmarking performance has always been the hottest topic. Who is faster for data ingestion and queries? About a month ago we announced a new release with SIMD aggregations on HackerNews and Reddit. Fast. But were those results numerically accurate?

SIMD instructions are specific CPU instruction sets for arithmetic calculations that use synthetic parallelisation.

InfluxDB is the current market leader in time series, and we thought it would only be fair if we had a stab at their ingestion format called InfluxDB line protocol (“ILP”) to compare data ingestion performance between QuestDB and InfluxDB.
