I subscribed to mailing list and of course I am gonna share my experience. I used log4Net for a while and as I know, log4Net keeps the file in memory so I assume the same for log4Php. I am using files and emails for Fatal level errors. I just wanted to give an example by saying 10000, but you are right 1 million log is not good idea. The best thing would be keeping critical logs such as delete etc. Thank you for all info Hello Christian,

About your question: no, Log4PHP doesn't hold logging events in memory. You can log to a file or to a database if you want to. For such an amount of users you are speaking, I would recommend to have only the most necessary statements logged. Most people are using error or warn level for production environments. This should only log few statements. But if you need such a heavy logging, you should consider logging to a database. Next question is: how much events do you create? Assuming 10000 visitors requesting 10 pages = 100.000 requests. If you create only 10 logging events you can expect 1.000.000 sql statements to be executed. Is your database ready for this? If not, I recommend you to have excessive logging on debug level only on test environment, for production only log on error level. This should result in few occasions. Hope that helped you a bit - hope to see you on the mailinglist. Maybe with some of your experiences :-) Best Christian Hi Serdar,

I searched but couldn't find too much info about performance. I think log4php keeps the log file in memory, lets say you have 10000 visitor/day, keeping sql and some information logs cost too much? Regards Hello Christian,
