We have 14,000+ test cases added to a test plan. When trying to view them in Execute tree, TestLink 1.8 has a performance issue. The tree structure either gets shown with a long delay, or the side frame errors with a 'page not found' error.
When this occurs, CPU usage peaks.
Even though TestLink 1.7 also has a similar performance issue, 1.8 looks more severe.
I guess the query for the tree structure has a room to be optimized.
