With SIX Swiss Exchange now up and running with its new SWXess platform, its technology supplier Nasdaq OMX can point to the fastest implementation of its X-Stream Inet matching technology, with average round-trip latencies of less than 40 microseconds. That's probably the fastest matching engine anywhere in the world today.
SWXess went live with equities trading on April 23, along with co-location facilities at an Equinix data centre in Zurich.
According to performance tests documented by the exchange, average round-trip latency at the exchange network domain boundary, using the Ouch protocol via a 10 gigabit/second Ethernet link, was 37 microseconds. That includes the time taken to validate, process, and acknowledge or fill a participant order.
As for the outliers, 99% of orders were processed within 78 microseconds, and 99.9% within 150 microseconds. Corvil latency monitoring devices were used to measure the latencies.
