Why Is Typesense Slow? High Latency Fixes

How to fix it

Try these in order — the most common fix is first.

1. 1. Move data closer to users

   Copy steps
   1. Typesense Cloud: enable Search Delivery Network (3 or 5 regions) in cluster configuration
   2. Set the Nearest Node hostname as the client endpoint and the nodes as fallbacks
   Did this fix it? Yes No

2. 2. Add CPU and avoid burst for sustained load

   Copy steps
   1. Move to more vCPUs, or more nodes for concurrency
   2. Check search and write latency in the cluster metrics
   Did this fix it? Yes No

3. 3. Separate heavy writes from reads

   Copy steps
   1. Use bulk import, limit workers to N-2
   2. Schedule big imports off-peak
   Did this fix it? Yes No

Symptoms

Search takes longer than the expected few milliseconds, latency spikes during imports or for users far from the cluster.

Why it happens

• Users far from the cluster region (for example about 76 ms added from Oregon to New York)
• Burst or too few vCPUs (minimum 2, and burst plans are not for sustained load)
• Heavy indexing at the same time as searches
• Large datasets lower throughput (docs example: 104 searches/sec at 2.2M records vs 46 at 28M on 4 vCPU)
• Slow disk
• Many unneeded indexed fields
