HTTPing is like 'ping' but for http-requests. Give it an url, and it'll show you how long it takes to connect, send a request and retrieve the reply (only the headers). Be aware that the transmission across the network also takes time! So it measures the latency of the webserver + network. All measurements can be viewed in a graph which can be shared.
