Hi, this is a basic asynchronous url response checker that I created and it's pretty fast, but I'm wondering if there is any way to get more requests per second with the base of this code. I have it designed so that it runs forever and just prints whenever there is a 404 in this example basically. I'm pretty new to python and coding in general and I would like some guidance/advice from anyone who has more experience with this kind of thing.. maybe there is an aiohttp alternative I should use that's faster? ANY advice is greatly appreciated.
