Orion logging..is it a performance hit?

[Duffey, Kevin]

I am curious..I look in the .log file created by each web-app and I see a
timestamp for every hit (each jsp page, gif, etc). I am wondering if this is
a performance hit..writing this info out on a regular basis (or is it
buffered and written when the server shuts down?). Also, is there a way to
turn it off if I don't much care for the hits. Finally..is there any way it
can be formatted so when opening it with WordPad or something it shows up
line by line, instead of without line breaks?

Thanks.
