## Performance - 50% Overhead Reduction
LiteLLM now sends 2.5× more requests to LLM providers by reducing wrapper function overhead across all endpoints.
### Before
```
============================================================
Fake LLM Provier Stats (When called by LiteLLM)
============================================================
Requests/Second: 10746.68
Latency Statistics (seconds):
Mean: 0.2039s
Median (p50): 0.2310s
Min: 0.0323s
Max: 0.3928s
Std Dev: 0.1166s
p95: 0.3574s
p99: 0.3748s
Status Codes:
200: 6000
```
### After
```
============================================================
Fake LLM Provier Stats (When called by LiteLLM)
============================================================
Requests/Second: 4224.49
Latency Statistics (seconds):
Mean: 0.5300s
Median (p50): 0.5871s
Min: 0.0885s
Max: 1.0482s
Std Dev: 0.3065s
p95: 0.9750s
p99: 1.0444s
Status Codes:
200: 6000
```
> The benchmarks run LiteLLM locally with a lightweight LLM provider to eliminate network latency, isolating internal overhead and bottlenecks so we can focus on reducing pure LiteLLM overhead on a single instance.
