# ⚡ January 19, 2026 - EVM Execution Engine Performance Optimization

> Massive performance improvement on EVM execution engine aggregator fallback, reducing p95 latency from 1s to 200ms

**TL;DR**: Dramatically improved EVM execution engine performance when falling back to external aggregators, with p95 latency reduced from 1s to 200ms (5x improvement).

## EVM Execution Engine Optimization

### Aggregator Fallback Latency Reduction

Optimized the performance of the EVM execution engine specifically for cases where we fallback to external aggregators:

| Metric          | Before | After | Improvement   |
| --------------- | ------ | ----- | ------------- |
| **p95 Latency** | 1000ms | 200ms | **5x faster** |

### Technical Improvements

* **Faster aggregator communication**: Optimized the request/response cycle with external aggregators
* **Improved connection handling**: Better connection pooling and reuse
