In the preceding table, you can see that we can maintain less than 100 ms per operation
(invocation) with audit / logging set to OFF in SCA. Of course, in production, the required
numbers are almost doubled. With some more fine-tuning, we could gain 10 to 15 ms
more, but apparently these numbers are rather inadequate for fast-running synchronous
transactions. This is just one obvious thing that we can spot immediately. We should con-
tinue improving the solution using a service-oriented approach.
Note
The presented numbers were achieved on a double CPU 2Core VM with 8 GB memory
and single node SOA Suite installation. All endpoints were mocked using SoapUI.
