remove/comment out addnodes in conf and add a connect=<node ip here> to download only from that node.
dont expect too much a speed boost, i sync capt once a week and it is ridiculously slow. hoping the dev will consider making hard fork to space out the blocks with increase block time.
I already did that before, and I'm still having the issue.
it's always 500 blocks then lots of unusable data for an hour give or take,
then it continues another 500 blocks and another hour unusable data, repeteadly
my question is why do I need to download/accept those unusable data?
I used debug option, and I think those unusable data are the latest blocks, not yet needed by my chain.
It only gives out partial hash and the online explorer doesn't take partial hash,
so I couldn't actually really compare them to the online blockchain explorer
