Automation Tasks slow and or freeze

We are facing issues with the automation tasks. They are very slow and often freeze. According to our hosting partner this happens because these tasks use to much memory. This happens mostly when running the “Generate thumbnails” and “Rescan files” tasks. On version 8 we never had these issues. What is causing this? More important how can we fix this? Thank you.
