how to cache generated sitemap using event populate?

[unclebee10]

Using sitemap generate through following these instructions and configuration to changefreq daily Dynamic routes usage but sitemap is being generated with every request and takes so long to load with huge populates, what would be best practice in such case?

I'm not sure I get this right
But it seems that you are not dumping your sitemap
If so, you should have a look to the dedicated documentation

The idea is that when you have big sitemaps (and I would recommend it even for small ones), you should not generate the sitemap every time, but generate it once and for all, and store it in your public dir
That way, your application server (Apache, Nginx...) shall serve the file, and Symfony won't be bothered at all
