Client success story
Optimizing WebSocket Order Book Latency for High-Frequency Trading
Partner client: BlockTrade Exchange
< 15ms
Order Book Sync Latency
10x
Concurrent WebSocket Connections
Zero
Trade Execution Dropped
The Challenge / Problem
During high volatility events, BlockTrade's UI order book lagged behind the matching engine by up to 2 seconds, causing failed trades and user frustration.
Our QA Solution & Architecture
Our engineering team deployed k6 and wscat to simulate 50,000 concurrent WebSocket connections and identify the exact event-loop bottleneck.
The Results & Impact
Guided the architectural shift to a Redis-backed pub/sub model, reducing order book latency to under 15ms globally.
