# this peer and the timing attack mitigation will be disabled in order
# to download data faster. The expected use case is where the user has
# a fast connection to a trusted server where they run a BitMessage
# daemon permanently. If they then run a second instance of the client
# on a local machine periodically when they want to check for messages
# it will sync with the network a lot faster without compromising
