Mapfile layers performance question

[Steve Hall]

Hi all,

Just a quick question.   Is there any (noticeable) performance hit in 
having a lot of layers in a mapfile with their STATUS set to OFF.   I 
don't want to use these layers right now but may need to switch them on 
at a later date, so it's convenient to have them in there, but not if 
they're affecting performance at all.....

Thanks,

Steve H
