Checkmk Werk 14499: activate changes: performance issues when synchronising users and user settings

ID: 14499 Title: activate changes: performance issues when synchronising users and user settings Component: Multisite Level: 1 Class: Bug fix Version: 2.2.0i1 The activate changes process could be slow when activating changes for multiple sites in a distributed monitoring set-up. The activation would eventually run into an error similar to "Failed to start activation [502]: Proxy Error". This was due to the implementation that synchronises users and user settings across all sites. Instead of copying these files in their entirety, a hard link is now created, reducing I/O on the monitoring server.
