What steps will reproduce the problem? 1. Open a project. Wait for indexing to finish. 2. Open a PHP class with intention to add a new public method. 3. Turn on CPU profiling. 4. Write "public fun", invoke code completion. 5. Everything hangs for 40+ seconds. Could be more. 6. Dialogue is displayed with a progress animation and "function" suggestion. 7. Finish CPU profiling. What is the expected result? No freezes on code completion. What happens instead? Feezes on code completion. Can't work with IDE at all when "show suggestions as you type" is enabled. Can't really use code completion without waiting for 40+ seconds every time it's invoked. CPU snapshot attached. The project It is https://github.com/yiisoft/yii-dev-tool with all packages installed and "yiisoft" added to ignored patterns so IDE doesn't go recursively into indexing symlinks. If you need help installing it locally, please don't hesitate to contact me.…
