Jim,
if you have any money to spend, it would be worth running a code
profiler
such as JProbe over the code. If you don't have access to such a tool /
money, then you could try running JMeter
As an aside, make sure you have all log4j Logger#debug statements
enclosed in if(logger.isDebugEnabled()) { ... } clauses -- that's an
order of magnitude or so runtime performance improvement.
Showing my C heritage here, but can't you do something like
Log(an error has occurred);
And in Log

Graham,
unfortunately, Java does not have a precompiler (although I think there are
some third party pre-processors about).

There is a hack to accomplish similar results.
If you declare a constant boolean variable as false and use it in your branch
statement the compiler will exclude the entire statement.
static final boolean DEBUG = false;
if(DEBUG){
//conditional code goes here
}

if you have any money to spend, it would be worth running a code

pre-processors), and can help the original poster.

Hi, Yoav,
I'll take a look at thos products. I wasn't aware of your other
suggestion. I assume you mean it will improve the performance when
debugging is turned off thus preventing the debug

I would expect that the Appenders and Formatters only come
into play if debug is enabled. Am I wrong ?
