A bug had been filed suggesting that Chrome download speeds (such as those measured by speedtest.net ) seemed to be affected by some anti-virus software. Downloads go through the cache, the cache is saved to disk, and saves to disk are slowed by (some) anti-virus software. It looks like this can happen.
