RE: [OT] log4j to file or db -- which will be faster
Howdy, System.currentTimeMillis() is good enough for the time of performance assessment you're doing.

Re: [OT] log4j to file or db -- which will be faster
A file will be faster unless your file system is really crappy or you are writing to a nfs mounted or other remote filesystem. (Even then it will still probably faster). IIRC, there is an ASyncronous appender which is a layer between your logging code and the real logger. What it does is queue up all writes so your application code can execute as quickly as possible. But it can only be configured via an XML file, not via properties files. -Tim Prabhat Kumar (IT) wrote: I know that this is too generic a question, but we have a requirement to log informational messages in our application about why certain actions were performed or not.
