[ebxmlms-develop] logging remark

[Ronald v. K. <rv...@ab...>]

Hi,

I've seen that all logging is done without checking whether the 
specified loglevel is even configured. We've seen in our Messaging 
System that first checking if a certain loglevel is configured gave us 
3-7% performance gain. This was due to the fact that on man ocasions xml 
-> string conversions were needed as well as string creation/concatenation.

So instead of

logger.debug("A message");

we now do

if (logger.isDebugEnabled()) {
    logger.debug("A message");
}

I do not know what the gain will be in hermes since i've not looked 
through all the code. It's probably not that much since debug info is 
not that detailed, but I thought I'd just mention it.
