How to quantify schema validation performance?

[jp4 <jo...@hnpsolutions.com>]

We are currently using CXF (2.2) with schema validation enabled.  I would
like to be able to quantify how expensive the schema validation is (i.e.
execution time in milliseconds).  I would like to do this for both inbound
and outbound validation.

Ideally, I would just wrap the spring bean using AOP to log the method
invocation.   If someone could point me to the beans (i.e. interceptors that
are used to perform the schema validation) it would be greatly appreciated.

Thanks,

John

Well, the validation is done DURING the JAXB reading/writing.   Basically, we 
feed the schemas to JAXB and it validates while its doing it's work.  Thus, 
you really cannot pull out the time that is spent validating.

What I could suggest is enable the management stuff:
http://cwiki.apache.org/CXF20DOC/jmx-management.html

which can record a bunch of metrics that would then appear in the mgmt 
console.   Run once with validation enabled, run again without and compare.
