Deribit upgrades matching engine, cuts median latency by roughly 61x
The Coinbase-owned derivatives venue swapped its Classic engine for Starbase, and the post-launch numbers show dramatic speed gains under heavy load
Deribit has replaced the engine at the heart of its exchange. The new system, called Starbase, cut median request-response latency from 4.7 ms to 76 µs, an improvement of approximately 61 times.
The more eye-catching number sits further out on the curve. Tail latency, the slowest 1% of requests, improved by roughly 531 times, which is why Deribit describes the upgrade as reducing latency by over 500 times.
What Starbase actually changed
Deribit’s previous system, known as the Classic engine, has now been retired in favor of Starbase. The new engine processes more than 100,000 orders per second with sub-millisecond matching.
Median latency fell from 4.7 ms to 76 µs. A microsecond is one-thousandth of a millisecond, so the typical order now completes its round trip in a small fraction of the time it used to take.
The p99 figure captures the slowest 1% of requests, and it dropped from 124 ms to 234 µs. Under the Classic engine, a trader’s slowest orders could hang for over a tenth of a second. Under Starbase, even the stragglers finish in well under a millisecond.

Post-launch data shows Starbase handling a peak of 23,836 requests in a single second.
Fairness, not just speed
Starbase enforces stricter FIFO ordering, meaning orders at the same price get filled in the order they reached the exchange. The engine also provides equal access for co-located traders at LD4.
On the connectivity side, Starbase adds low-latency APIs using SBE over TCP and UDP multicast. SBE, or Simple Binary Encoding, is a compact message format designed for speed, and multicast lets an exchange broadcast market data to many recipients at once rather than one by one.
The Coinbase connection and the rollout timeline
Starbase arrives after Deribit’s acquisition by Coinbase. The launch is part of Deribit’s deeper integration with the Coinbase International Exchange, framed as a strategy to improve performance and scalability.
A testnet opened in April 2026, giving traders a sandbox to test their systems against the new engine before real money was involved. Production deployment followed in early July 2026. Deribit then published detailed performance metrics on September 21, 2026.
