为什么 gevent 比多进程慢那么多？是不是只有 gevent 作为 http 服务器的时候才有优势？对于这种主动请求的没优势？
gevent:40 秒 --------------------------------------------------------------- start_time = time.time() urls = ('http://www.baidu.com' for i in range(10000)) jobs = [gevent.spawn(requests.get, url) for url in urls] #print(jobs) gevent.joinall(jobs) #print([job.value.status_code for job in jobs]) end_time = time.time() print(end_time - start_time) ---------------------------------------------------------------- multiprocessing：12 秒 ---------------------------------------------------------------- def req(url): return requests.get(url).status_code if __name__ == '__main__': start_time = time.time() p = Pool(32) res_l = [] for i in range(10000): res = p.apply_async(req, args=('http://www.baidu.com',)) res_l.append(res) p.close() p.join() #print(len([i.get() for i in res_l])) end_time = time.time() print(end_time - start_time) ----------------------------------------------------------------
