I run zcashd on an Ubuntu system but I don’t often sync with the network more than once per week. The last time I did this the process was very slow and I was often looking at the System Monitor as I waited. My wallet was roughly 3500 blocks behind and by the time it had synced almost 1GB of data had been downloaded. Is the Zcash blockchain growing that much in a week? If not, why is so much data required during syncing and why has syncing become so slow?
the last week had those crazy big transactions when Poloniex was doing all those wallet sweeps, and its the verification time for them that’s slowing down syncing.
