Any time you copy huge files from one machine to another, it takes a long time. Since QuickFinder uses the HTTP PUT protocol for security reasons to synchronize the indexes, it takes even longer. However, the part of the communications pipeline that takes the longest is the use of the HTTPS (SSL) protocol. We have found that indexes synchronize 10 times faster between machines if admins use the HTTP protocol which can be configured in the Global Synchronization Settings page. Besides, if the sending and receiving machines are already both behind the corporate firewall, then there’s no need to have the added security.
