Import module slow

Is it reproducible? Is project located on local disk?

If problem remains with the version from https://www.jetbrains.com/idea/download please take several jstack thread dumps when at the moment when it is searching for modules with this dialog and attach them and IDE log folder zipped. 

For uploading you can use ftp://ftp.intellij.net/.uploads / https://uploads.services.jetbrains.com or any file sharing service.

Try with antivirus/firewall disabled or make sure that IDE settings directories IDE installation home and project files are excluded from the scan.

If issue remains provide jstack thread dumps of IDE process at the moment of issue.
