In single core, a restart of Solr is required to pick up changes to  
most* configuration files.  In multi-core, cores can be reloaded  
through an HTTP command, however I believe searches will be  
unavailable during that core startup which can be a significant amount  
of time (minutes or so, most I've seen with heavy warming query  

* DataImportHandler can reload its configuration files with an HTTP  
command.  And some other files can be picked up dynamically (like  
VelocityResponseWriter templates).
