qdrant-performance-optimization

A guide for improving Qdrant’s speed and memory use. Qdrant is a database for searching numerical representations of data.

In plain words
What is it for?
Use it to choose guidance for faster searches, quicker indexing, or lower memory use, including decisions about CPU, disk, segments, and replicas.
Why use it?
It helps separate planned performance tuning from investigating a live slowdown or production incident.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

qdrant-performance-optimization scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Qdrant Performance Optimization

Usage

You say What happens
"Speed up indexing/search" / "reduce memory usage" Use this hub to route to the matching sub-skill (search-speed, indexing-performance, memory-usage) — check whether the real bottleneck is the onnxruntime-gpu/CPU fallback trap (AGENTS.md's Database section) before tuning Qdrant-side parameters.
"Qdrant is slow right now / in production" Use qdrant-monitoring instead — this skill is for proactive tuning, not live incident diagnosis.

There are different aspects of Qdrant performance, this document serves as a navigation hub for different aspects of performance optimization in Qdrant.

Search Speed Optimization

There are two different criteria for search speed: latency and throughput. Latency is the time it takes to get a response for a single query, while throughput is the number of queries that can be processed in a given time frame. Depending on your use case, you may want to optimize for one or both of these metrics.

More on search speed optimization can be found in the Search Speed Optimization skill.

Indexing Performance Optimization

Qdrant needs to build a vector index to perform efficient similarity search. The time it takes to build the index can vary depending on the size of your dataset, hardware, and configuration.

More on indexing performance optimization can be found in the Indexing Performance Optimization skill.

Memory Usage Optimization

Vector search can be memory intensive, especially when dealing with large datasets. Qdrant has a flexible memory management system, which allows you to precisely control which parts of storage are kept in memory and which are stored on disk. This can help you optimize memory usage without sacrificing performance.

More on memory usage optimization can be found in the Memory Usage Optimization skill.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

qdrant-performance-optimization is a skill published in the GitHub repository SecondLifes/code-intel (2 stars, last pushed 21d ago), licensed Apache-2.0. It adds 63 tokens to every session and 505 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
