RE: How to measue performance? Log4j on/off.
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 to benchmark the site.

We have a performance issue with a web page being served via Tomcat/Apache. I don't think it has anything to do with Tomcat, but I am being asked to turn debug logging off to help improve it. I'm resisting because the output has been extremely valuable in solving problems that still crop up and to find out what the users are really doing as opposed to what they said they did. That said, is there a definitive way I can compare the performance of the site before and after turning the logging off? Other than a stopwatch?

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

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 have a directive like
class Logger()
{
void Log(string msg)
{
#ifdef DEBUG
... log message ..
#endif
};
And so you can compile a version with debug or no debug. Those if()
statements are still going to take time to process, even if there is no
logging going on.

RE: Hosting SSL clients within Tomcat
FYI, I have now cracked this problem. I had something of an epiphany last night -) The problem lies with Bill Gates! The default .keystore is created in the current Windows users home directory. The path to this directory has a white space in it, which the JVM does not like. If you try and use your own keystore, Tomcat does not like it. The trick is to create the default .keystore file, import your client certificate and then copyt the .keystore to another location with no white space in the path. You then specify the location of the .keystore and the password for the store on the line in the catalina.bat file that starts Tomcat. Obvious Of course the better alternative is to develop and host using Linux or Solaris (but my client won't do that!!!)
