The profiler pointed at Rust code we'd assumed was free. We followed the trail all the way down to assembly to find the true cost.

Thu, 12 Feb 2026 00:00:00 GMT https://turbopuffer.com/blog/ann-v3 https://turbopuffer.com/blog/ann-v3 Our latest ANN release supports scales of 100+ billion vectors in a single search index, with 200ms p99 query latency at 1k QPS and 92% recall. Wed, 21 Jan 2026 00:00:00 GMT https://turbopuffer.com/blog/fts-v2-postings https://turbopuffer.com/blog/fts-v2-postings How we redesigned our inverted index structure using fixed-sized posting blocks to achieve 10x smaller indexes and dramatically better throughput. Wed, 14 Jan 2026 00:00:00 GMT https://turbopuffer.com/blog/bm25-latency-musings https://turbopuffer.com/blog/bm25-latency-musings I analyzed how BM25 query latencies scale with document count and top_k. Longer queries scale less efficiently, and essential terms impact performance in some surprising ways. Wed, 07 Jan 2026 00:00:00 GMT https://turbopuffer.com/blog/fts-v2-maxscore https://turbopuffer.com/blog/fts-v2-maxscore turbopuffer has improved text search performance up to 20x by adopting the same text search algorithm as Apache Lucene, a vectorized variant of block-max MAXSCORE Tue, 09 Dec 2025 00:00:00 GMT https://turbopuffer.com/blog/fts-v2 https://turbopuffer.com/blog/fts-v2 turbopuffer's full-text search engine is getting a major upgrade for 20x better full-text search performance Thu, 04 Dec 2025 00:00:00 GMT https://turbopuffer.com/blog/native-filtering https://turbopuffer.com/blog/native-filtering Describing how turbopuffer ensures high recall (accuracy) on queries that use attribute filters. Tue, 21 Jan 2025 00:00:00 GMT https://turbopuffer.com/blog/continuous-recall https://turbopuffer.com/blog/continuous-recall Describing how turbopuffer measures the recall (accuracy) of its vector indexes in production continuously. This ensures that turbopuffer's search results are accurate and reliable, despite using approximate nearest-neighbour algorithms to speed up queries. Wed, 04 Sep 2024 00:00:00 GMT https://turbopuffer.com/blog/turbopuffer https://turbopuffer.com/blog/turbopuffer Inaugural blog post about the development of turbopuffer, a search engine that uses object storage and SSD caching for cost-effective, low latency search. This post describes into the motivation behind its creation, its unique architecture, and how it significantly reduces costs for large-scale vector searches. Discover how turbopuffer is transforming search infrastructure for companies like Cursor and Suno, offering a scalable and reliable solution. Mon, 08 Jul 2024 00:00:00 GMT
