Does IE10 use some sort of compression or acceleration?

[Engineer]

My Internet speed is around 14Mbps download. Every download test run on Firefox gives me about those numbers, including:

www.testmy.net

When running IE10, the test is visibly faster and the downloading speed results in 17.5 to 18.5Mbps.

Other tests, such as www.speedtest.net give the same results on all browsers (around 14Mbps).

What am I missing here?

nope, mine is other way around
ie10: 15mbps
ff19: 22mbps
My guess is that speed varies greatly over both short and long time periods.
Also data is claimed to be random, so that it cannot be compressed.

It sounds like a flawed test. A browser could parse and render the downloaded payload faster, but it should have no effect on network transmission. The only possible exception would be Chrome's implementation of the SPDY protocol (which only works if the server supports it), but for 99 percent of the cases all browsers should be using the same protocol over the same connection and thus the download speed should remain unchanged.
