NexusFIX is a high-performance FIX protocol (Financial Information eXchange) engine built for ultra-low latency quantitative trading , sub-microsecond algorithmic execution , and high-frequency trading (HFT) systems. It solves the performance bottlenecks of traditional FIX engines by utilizing hardware-aware C++ programming . NexusFIX serves as a modern, faster alternative to QuickFIX with zero heap allocations on the critical path. \"If you're building a low-latency trading system and QuickFIX is your bottleneck, NexusFIX is your solution.\" --- Performance NexusFIX vs QuickFIX Benchmark Tested on Linux with GCC 13.3, 100,000 iterations: Metric QuickFIX NexusFIX Improvement -------- ---------- ---------- ------------- ExecutionReport Parse 730 ns 246 ns 3.0x faster NewOrderSingle Parse 661 ns 229 ns 2.9x faster Field Lookup (O(1) post-parse, 4 fields) 31 ns 11 ns 2.9x faster Parse Throughput 1.19M msg/sec 4.17M msg/sec 3.5x higher P99 Parse Latency 784 ns 258 ns 3.0x lower Why is NexusFIX Faster?
