I've removed by blockchain information and started redownloa= ding it, on a fast connection, using the latest git version (tagged v0.7.1r= c1), on a SSD disk.

Everything goes very fast, except that a lot of = duplicate blocks are processed. New blocks arrive quickly, then a lot of du= plicates seem to be processed at a much quieter pace, while the chain heigh= t does not increase anymore.

Is that expected? Isn't there a way to limit unneeded blocks downlo= ads?
