<answer>
|

You've probably enabled logging. Logging is intended only for
|
||||
autopsie style debugging. Having it enabled will reduce performance
|
||||
by a factor of at least 100. Logging is helpful for understanding
|
||||
why POI can't read some file or developing POI itself. Important
|
||||
errors are thrown as exceptions, which means you probably don't need
|
||||
logging.

Logging in POI is used only as a debugging mechanism, not a normal runtime

logging system.
|
||||
logging system. Logging is ONLY for autopsie type debugging, and should
|
||||
NEVER be enabled on a production system. Enabling logging will reduce
|

performance by at least a factor of 100. If you are not developing

POI or trying to debug why POI isn't reading a file correctly, then DO
|
||||
NOT enable logging. You've been warned.
