I was looking at your tutorials and everything is great. I have made a spider and tried to scrape a website. It works but after it crawles somw time it starts to slow down and finally the computer block or the spider gets killed.. I have not use venv. Is this the cause or do I have to do something else. The web site I scrape is very big.Thank you

Great Explanation ! Thank you so much. One small question: if I have used spider to extract links but now I know that crawlspider can do the same thing do I need to rebuild it with crawlspider ? Is the performance worth rewriting ?
