Every spider process is a browser tab. People have hundreds tabs opened without any problem on ordinal computers. On a dedicated server with 128GB of ram you can run thousands of those and it will cost you 100$-200$/month.
- jasonjayr 9y agoTrue -- But the user is not interacting with all 100's of those tabs at the same time -- something an automated scraper would be. Firefox + Chrome both lower the priority of background tabs, and may be doing other tricks so the background tabs can stick around and be switched to quickly.
- Dolores12 9y agoWell, most of the time spiders are idle while waiting for IO operations to complete. Main bottleneck is not CPU, but RAM and bandwidth.
- rileymat2 9y agoIt depends on what analysis is being done on each page.
- Dolores12 9y agoWhat kind of analysis are you expecting from a crawler which main purpose is to grab a webpage?
- ivanhoe 9y agoMain purpose is to render the page, crawl the dom for the data, and then load the next page as fast as possible... so it's equivalent of having a thousand bookmarks and opening them all at the same time, and as soon each loads running the scraper script and reloading them with the new link. Try it for yourself, it's easy to script, and check the load...
- rileymat2 9y agoPresumably, there is some reason you are crawling.
