Simulated benchmark tests carried out on InterComponentWare’s LifeSensor personal health record (PHR) have shown that the system can handle 10,000 concurrent virtual uers and 10m records.

Germany’s ICW conducted the test over a ten-day period at the Hewlett Packard European Performance and Benchmark Centre, Stuttgart, Germany.

According to ICW the performance test verified LifeSensor’s capacity, scalability and performance under extreme conditions.

As well as simulating access by 10,000 virtual users to a database consisting of 10m PHRs the tests also simulated use by 20,000 virtual doctors and pharmacists.

The same HP centre last March tested the scalability and resilience of iSoft’s Lorenzo software product, currently under development. 

Peak loads during performance testing were reported as showing up to 700 PHRs could be accessed simultaneously, with system performance still remaining stable. ICW say this indicates that over “a prolonged period of time up to 8,500 users could process personal health records at any given time”. At peak times more than simultaneous virtual users were online.

“ICW has done exemplary work in designing and developing the LifeSensor health record platform. Running on HP’s hardware, LifeSensor delivers outstanding results and fulfills the requirements of markets worldwide”, said Hans-Jurgen Preuss, sales manager for the health sector of Hewlett Packard, Germany.

Peter Reuschel, CEO of ICW added: “Personal health recordplatforms need to be scalable, highly accessible, stable, and above all secure, so that users and health care providers can use the records anytime world-wide.”

The LifeSensor PHR is the second of ICW’s products to be tested in HP’s European Performance and Benchmark Centre. ICW’s Master Patient Index (MPI), another component of the firm’s Professional Exchange Server, has already been successfully tested at the centre.
