Magento Performance: Admin area on separate server
Magento provides a rich admin panel to manage all aspects of store(s). Admin panel operations are resource consuming because it does not use much cache etc. The pages also consume more memory.
So its good idea to dedicate a separate web server for admin panel operations. This way one may customize certain setting for admin area. This can be done by having a synced copy of Magento code on moth servers, and setting the admin url to new server. Option can also be configured during install.
