Hello,
1) Check all the enabled plugins and disable all the plugins that you don’t really use. Don’t keep them enabled just in case.
2) What number of product do you use at your shop page and for the Product slider elements if you use them on your pages? If you have problems with request amount then we would not recommend you to use Infinite scroll plugin, disable it and reduce number of products at the shop page to 12-15
3) Change server and cache plugin settings to fix these items http://prntscr.com/qc5q95
All the requirements are listed here https://xstore.helpscoutdocs.com/article/60-xstore-theme-requirements Your params should be no less than mentioned limits.
Regards
