"Timeout" is the wrong term here. It's more accurate to say "response time". "Timeout" means that something failed because it took too long, whereas what you're measuring here is the time taken before it succeeded. 2. Why is the HTTP response time higher than the ICMP response time? Because compared to ping running over ICMP, HTTP is a complicated protocol, running over TCP, which is a complicated, multi-stage protocol, and the response has to be generated by an application on the remote server, which is probably fetching content from a storage device in order to send it to you. An ICMP ping requires just a single packet from your machine to the target, a simple response in the network stack, and a single packet back to you in return. > is there a way in squid to make it faster and few http ms like 30 ms ? It's not Squid which is taking the time - it's the remote server - try measuring it without Squid in place and see what the response time is.
