When a 4D Remote Client connects to a 4D Server, a cache of files and resources are made on the local machine for performance so additional requests are not needed when accessing these items. There are some things that will cause the Server to let all of the connected clients know that something has changed and they will need to update the item. This is a major process that can impact performance. As such ,it is suggested to avoid performing such actions frequently.

Some examples of these actions are:

• Modification of Users and Groups
• Modification of static lists and menus
• Modification of Database Resources folder

While it is ok to perform any of the above, it is suggested that these actions be performed sparingly when needed.
