 Indexing is a memory-intensive and multi-threaded operation. The more memory and processor cores available, the faster Meilisearch will index new documents. When trying to improve indexing speed, using a machine with more processor cores is more effective than increasing RAM.
 
 Due to how Meilisearch works, it is best to avoid HDDs (Hard Disk Drives) as they can easily become performance bottlenecks.

+## Enable binary quantization when using AI-powered search
+
+If you are experiencing performance issues when indexing documents for AI-powered search, consider enabling [binary quantization](/reference/api/settings#binaryquantized) for your embedders. Binary quantization compresses vectors by representing each dimension with 1-bit values. This reduces the relevancy of semantic search results, but greatly improves performance.
+
+Binary quantization works best with large datasets containing more than 1M documents and using models with more than 1400 dimensions.

+**Activating binary quantization is irreversible.** Once enabled, Meilisearch converts all vectors and discards all vector data that does fit within 1-bit. The only way to recover the vectors' original values is to re-vectorize the whole index in a new embedder.
