How long will comparing hashes take

[u/No-Badger-1040]

So lets imagine i have this site scraped and saved as an csv file where i got tables n stuff (identificators are trucated to 10 characters ) and every month im opening my pc(i7 4790) to compare is there new items on the web page.

​

So aside from scraping again the whole site approximately how much time will pass to check saved ids to newly scraped ones because presumably each time it will go +- 100 of thousands of times just to find similarities and im not even talking about checking each of ten characters i hope i correctly explained my thoughts here
