London Stock Exchange Reports Halved Latency Following Data Center Migration

The London Stock Exchange completed a data centre and hardware upgrade of the exchange itself, Turquoise and TRADEcho services, to a new dedicated facility in London in February, as a means of improving latency. According to the exchange, the move has seen a 50% reduction in average round trip latency for the equities order book, as well as ‘outlier’ observations in the distribution reducing by 75%, LSE said. LSE’s ETF order book has seen a 66% reduction in average round-trip latency, with outliers down by 80%. “LSEG is delighted to confirm that it has successfully migrated its trading and market data systems to a new highly efficient, purpose-built data center near Docklands, London. The new data center will deploy the latest technology to continue to deliver high levels of performance, security and resiliency, for the benefit of our markets and customers,” a spokesperson for LSEG said.  Elsewhere, data from the trading venue has indicated that it has increased its FTSE 100 European Best Bid and Offer (EBBO) setting by 9% compared to the period before the data center move – accounting for over 40% of all EBBO setting events.
