I have a website running on Nopcommerce 4.5 which has approx. 2 million Product/Category/Blog URLS and more coming soon.
The sitemap is very slow when opened looking at the fact it creates it in runtime. I also add approx. 200k+ custom URLS from a text file into the sitemap.
Keeping the above in mind should I still be using the built-in sitemap functionality?
Is it normal for sitemap to take such a long time? example the sitemap can go up to
sitemap-135.xml (I add 10k URL per sitemap). Will this be an issue with google indexing the URLS, please let me know if I should follow some other route.
Thank you
