The LSE says the Performance Channels service ensures data distributed by Infolect is delivered at high speeds even during peak trading times. The service is available through 100 megabyte Extranex lines, cutting the average round trip network latency within the City to below one millisecond.

Says David Lester, CIO, LSE: "The Performance Channels service gives member firms using algorithmic trading models greater visibility of the spikes and events that occur during periods of high trading activity. The immediate delivery of price data during these peaks creates additional trading opportunities."

The new service has been launched to help firms deal with increased trading capacity and market data volumes following the introduction of the LSE's TradElect platform. The £40 million trading system, which went live last June, was designed to raise capacity fivefold and position the market for higher volume automated dealing.

A pilot of the Performance Channels service has been running since TradElect went live. The trial saw customers participate in a series of conformance tests to ensure their network infrastructure could cope with the strain generated by higher peaks in data volumes.

LSE says over 40 customers have already signed up to the Performance Channels service.
