System overloaded due to a change in the smb.conf

We had a case here where we got significant delays due to smb.conf being read/refreshed by a LOT of clients on HP-UX, but the smb.conf file in question was pretty huge.  How big (how many bytes) is your smb.conf file?  do you have includes in it, and how big are they?

an operation...
