I see the same effect. I’m on Studio 2021.10.8
My flow is relatively complex, interacts with an excel file (small) but no image collection/data scraping.
I see that my PC ram usage from Studio is close to 3GB
Just performing ordinary copy/paste or move around the flow they become very unresponsive after a couple of runs on DEBUG mode. My desktop is relatively powerful (64GBram, intel xenon 2125 4.00Ghz)
Any clue?
