[castor-user] General performance problem

[Johannes Rauber]

Hi,

while implementing castor as our xml marshaller, i did some performance
measurements. The marshalling and unmarshalling
performance is orders of magnitude lower than with JAXB. This strikes me
as odd, i expected a little increase but not as much as this.
With Jaxb I get 1800 transactions per second, with Castor just about
10-12. I' am using castor 1.2 with java 1.6.
Could you help me out finding where it goes wrong?

Side and Currency are simple enum's
