Changing the architecture of the Ericsson Billing Gateway application has shown to solve the problem with dynamic memory management that decreased the performance. The new architecture that is focused on processes instead of threads showed increased performance. It also allowed for the possibility to adjust the process / thread configuration towards the network topology and hardware. Measurements of different configurations showed the importance of an accurate configuration and also that certain guidelines could be established based on the results. / Genom att ändra architecturen på Billing Gateway löste man på Ericsson problemet med "Dynamisk minneshantering". Den nya architecturen som fokuserar på processer istället för trådar visade ökad prestanda. Den nya architecturen tillät också vissa konfigurationsmöjligheter gentemot nätverkstopologi och hårdvara. Mätningar på olika konfigurationer visade vikten av rätt konfiguration och också att vissa riktlinjer kunde utrönas från resultaten. / Phone#: +46 457 66582

In this report we evaluate different techniques for increasing the performance of an interpreted processing language in a telecommunication system, called Billing Gateway R8. We have implemented a prototype in which we first translate the language into C++ code, and then compile it using a C++ compiler. In our prototype we experienced a threefold increase in processing throughput, compared to the original system, when running on a Symmetric Multi Processor with four CPU:s that were under full load. The prototype also showed better scalability than Billing Gateway R8, due to less use of dynamic memory management.
