One of the biggest issues we notice and complaints we get from clients is the amount of RAM the system takes up after using it for a while. The more you move around inside GHL, the slower it gets. It seems like all of the individual applications stay running in the same browser window even if the screen changes. Sometimes a reload helps. Sometimes we have to completely close the tab and reopen it. There needs to be memory dumps to keep this from happening and keep the system running fast for the users.
