If it saves network bandwidth, then you just have to measure the network bandwidth, like a speedtest page does. As Spectre and friends have shown, even the tiniest difference can be used for an information leak.
- icebraining 7y agoThe speedtest pages work by measuring the time it takes to download a file. If the browser used a simulated time length, then the "bandwidth" will look the same.
- AgentME 7y agoThe attack idea is that a site could check if a file is cached by downloading a test file at the same time and seeing if the test file download speed is affected.
