| | 150 | QCG-Notification performance was compared to the performance of two other services implementing brokered version of WS-Notification specification. These were Apache ServiceMix (version 3.3.1) and IBM WebSphere Application Server (version 7.0). |

| | 152 | A reliable performance tests of the notification systems are difficult to realise. Note that the distribution time of a single, small SOAP notification message can be easily disrupted by underlying best effort transport protocols, network protocols, services, etc. Therefore the presented results refer to the average notification delivery time measured on a basis of significant amount of singular sends. |
| | 153 | |
| | 154 | Taking into account that the tested notification systems are different: each system provides a set of specific functions that is not always the same in the another systems (for example, ServiceMix doesn’t provide support for Full topic dialect) decision was to test the most common features and focus on key scenarios. |
