The London Stock Exchange boasts a new record speed with a latency as low as 126 microseconds. The earlier latency went way over 1000 microseconds, which was also affecting trading speeds. However, the changeover to Linux has proven beneficial in more than one ways.
The London Stock Exchange is still in transition and will announce a complete switchover on 1 November 2010. It has proudly claimed that its main international rival performs at half that speed and the older exchanges ran at a speed of 300 to 400 microseconds. The new system has been implemented replacing the earlier .NET technology powering the LSE. More news on the switchover can be seen in this earlier coverage.
The new system is being tested in three phases out of which phase one and two are already done with. Phase 3 is the last test. The new system has performed exceptionally well and will perform well as there is a 0.1 percent chance of the system going above 400 microseconds of latency. What remains is the transition of users to this new system. However, it is said that the test phase one was rigorous enough to gain the trust of experts who supported this move.
