Python Requests-futures slow

Question

I'm currently using requests-futures for faster web scraping. The problem is, it's still very slow. Around 1 every other second. Here's how the ThreadPoolExecutor looks:

        with FuturesSession(executor=ThreadPoolExecutor(max_workers=8)) as session:
            futures = {session.get(url, proxies={
                'http': str(random.choice(proxy_list).replace("https:/", "http:/")),
                'https': str(random.choice(proxy_list).replace("https:/", "http:/")),
            }, headers={
                'User-Agent': str(ua.chrome),
                'Accept': '*/*',
                'Accept-Encoding': 'gzip, deflate, br',
                'Connection': 'keep-alive',
                'Content-Type': 'text/plain;charset=UTF-8',
            }): url for url in url_list}
            # ---
            for future in as_completed(futures):
                del futures[future]
                try:
                    resp = future.result()
                except:
                    print("Error getting result from thread. Ignoring")
                try:
                    multiprocessing.Process(target=main_func, args=(resp,))
                    del resp
                    del future
                except requests.exceptions.JSONDecodeError:
                    logging.warning(
                        "[requests.custom.debug]: requests.exceptions.JSONDecodeError: [Error] print(resp.json())")

I believe it's slow because of the as_completed for loop since that's not a concurrent loop. As for the main_func I pass the response to, that's the function that uses the information from the site using bs4. If the as_completed for loop would have been concurrent, then it would still be faster than this. I really want the scraper to be faster and I feel like I'd like to keep using requests-futures, but if there's something that's a lot faster, I'd be happy to change. So if anyone knows something that's quite a lot faster than requests-futures, then please feel free to share that
Is anyone able to help with this? Thank you
