Performance

One benchmark harness, two products.

reamer_research measured head-to-head against Backtrader and QuantConnect LEAN. Reamer Server benchmarks documented separately.

vs. Backtrader & LEAN

Reamer Research

Throughput on the same machine, same data, same strategies.

76x–212x faster than Backtrader and QuantConnect LEAN across single-ticker and 50-ticker portfolio workloads, at every tier tested — full methodology and every result table.

Reamer Server

30ns native ABI overhead. 23-69µs cgo end-to-end latency.

Core-to-local-acceptor benchmarks: native C++ ABI (pure vtable call cost) and cgo reference implementation (socket I/O + Go/C boundary). Institutional EMS and venue round trip dominate end-to-end execution latency; Reamer Server core contributes less than 2% to typical deployment latency.
