Has anyone got any experience of fine tuning change notification using the registry settings for "Replicator notify pause after modify" and "Replicator notify pause between DSAs" ?  Currently looking at a set of requirments where we need changes replicated between dozens of DCs in as short a time as possible.  Less than the default 15sec/3 sec values would allow.  Not something ive ever had the need to change so curious if anyone else has or has any views on it.  Thanks
