I’m doing some work about using proxy server to visit websites.I learnt about these two different proxy servers but I wanna know more about the differences between these two proxy.Here are the questions.
1.I know that tunnel proxies have one more central node than direct proxies to send request.And I searched that it’s safer than direct proxy, but I don’t know how safe it is? And what technology makes it safer？
2.The business I am currently doing requires high time consumption.(response time need to be in 1 second) The tunnel proxy I used could hardly meet my needs. And I wonder it’s the quality of the proxy server or because of the central node that costs time?

response time of tunnel proxy serversThis is the picture of the cost time of using tunnel proxy servers that could meet my needs but they cost too much.
response time of direct proxy serversDirect proxy servers are much better,But I wonder why some business take such long time?Sometimes they are so fast and sometimes so slow, how can I troubleshoot these problems?
