Is this more fore clients being overloaded?  (say user is swapping some)

Changing options like this does it take affect only for new mounted  
clients?  Or is it forced to all currently mounted clients?

Should this only be done on a 'down' filesystem?  Or can conf_param  
values be changed while live?

Thanks
