P99 order delay reduced to 3.76 milliseconds, Polymarket's new trading system Nex opens sandbox testing

Odaily Planet Daily News: Josh stated that the new trading system Nex, rewritten in Rust, has opened sandbox testing. For the past week, it has mirrored production orders in shadow mode to verify latency, load stability, and matching accuracy, but it has not yet been officially launched. Internal test data shows that order placement latency P99 has dropped from 1.55 seconds in the current central limit order book (CLOB) to 3.76 milliseconds, though this metric does not represent end-to-end latency. The team plans a four-week shadow testing period, and if performance remains strong, the system is expected to go live by mid-December, with WebSocket improvements possibly launching earlier.
