At the moment, freshclam makes a HTTP download on two CVD files, which at the moment are 965Kb and 92Kb. It does this download whether the file is different or not, so the load on the servers is much higher than it needs to be, but the load on clients is minimal. Far better would be to download a (GPG signed?) version file of maybe 2Kb, process this to work out whether we are up to date, and if not, then download the new file(s) in their entirety.
