Steady latency when volume spikes
Profiling and parser work that removed allocation pressure from the FIX message path, cutting tail latency when traffic bursts.

The problem
A system that is fast on a quiet day can slow down exactly when it matters most. During volume spikes, allocation and garbage collection push tail latency up.
What I built
- Profiled and resolved processing degradation during volume spikes
- Eliminated allocation pressure in the FIX message parser
- Reduced garbage-collection pressure on the hot path
Why it matters
Tail latency dropped on burst traffic, so the system stays fast on the busiest days, not just the quiet ones.
