R4J Configuration Option
Maximal visible sub-items in tree
Limit the number of items (folders, issues, pages) listed under any item in the tree view.
To optimize the tree view capabilities, a limit may be configured so that only necessary information is loaded.
Minimum free needed memory to process coverage
Specify the percentage of free memory required to continue processing a coverage view rendering or export.
Processing a large coverage view may cause a Jira instance to become unstable (or even crash). This configuration prevents such behavior by specifying a free server memory (max memory) threshold to be respected during a coverage view process. If this value is reached, the coverage view process will stop, guaranteeing the server stability.
This value may vary depending on your server instance. It is influenced by different factors, such as server configuration, available memory, dedicated heap memory size, third-party plugins installed, and so on. The default setting can be lowered to improve customer satisfaction.
Number of levels expandable in tree
Specify number of levels that can be expanded at one time in the tree view of R4J activated projects.
Select from level options: None, 2, 3, 4, 5, All.
Note that allowing to expand all is known to cause performance issues.
