High-traffic LiteLLM proxy
For: Platform teams running a shared LiteLLM proxy
When many services share one LiteLLM proxy, the bottleneck under load is usually connection-pool contention, not the model call. Fast LiteLLM's lock-free Rust connection pool is 3.2× faster and drops in via a preload wrapper — no gateway config changes.

The problem
- →Latency climbs under concurrency even though providers are healthy
- →Connection-pool locks become the hot spot at peak traffic
- →Adding workers helps less than expected
How Fast LiteLLM helps
Lock-free connection pool
A DashMap-backed pool removes the per-provider lock contention that dominates at concurrency — 3.2× faster in our benchmarks.
Preload-friendly
A one-line wrapper module plus gunicorn --preload lets every worker inherit the accelerated components.
Safe rollout
Feature flags and canary percentages let you enable acceleration on a fraction of traffic first.
