Why are requests slower through Crawlera than other proxies?
If you’re using your own proxies, you may notice a discrepancy in speed between using your own proxies and using them with Crawlera. This is because Crawlera throttles requests by introducing delays to avoid being banned on the target website.
These delays can differ depending on the target domain, as some popular sites have more rigorous anti-scraping measures than others. Throttling also helps prevent inadvertently bringing down the target website should it lack the resources to handle a large volume of requests.
