The Petals topology used is the default one (standalone mode, Petals ESB 3.0.5, JDK 6)
The BC SOAP (4.0.2) and SE POJO (2.2.2) are installed (the XSL transformation and backup are packaged into a JAR to prevent side effects)
The servers used are:
- 32 bits: 1.7 GB memory/1 EC2 Compute Unit (1 virtual core with 1 EC2 Compute Unit)/160 GB instance storage
- 64bit: 68.4 GB memory/26 EC2 Compute Units (8 virtual cores with 3.25 EC2 Compute Units each)/1690 GB of instance storage
Note 1: An EC2 Compute Unit is same as a 2007 Xeon processor
Note 2: Operating system: Linux Debian, the last version available in 2010, September/October.
The 32bits server is more powerful than the 64bits:
- 32 bits: 150 msg/s
- 64 bits: 20msg/s
