[SmartCrawl Pro] SmartCrawl and performance losses


Since we activated SmartCrawl, we often suffer from strong performance losses. Storing an article takes several seconds, and saving a menu sometimes even creates timeouts on the database and lets the server deliver a 503 while it is saving. Other similar behaviors follow.

We have nearly 2000 articles, the automatic generation of the SiteMap is switched off. Once SmartCrawl is disabled, the system behaves normally again. We would like to use the plugin for SEO, can you help us, what we can improve?
