I'm running Linux Mint 17.3 and I'm trying to update my ethereumwallet. I'm around 1.4 million blocks behind, so I started the ethereumwallet last night before going to be and I see that after 8-9 hours up updating it's moved from 2.6million to 2.7million of 4million blocks. so by my math it's going to take somewhere between 104-208 hours to finish updating my node. so googling took me to "How can I get a geth node to download the blockchain quickly?"
where they said to use "geth --fast --cache=1024 --jitvm" well "geth" did nothing for me so I tracked down the ethereumwallet executable in the "opt" folder and launched with those flags only I increased the cache to "10240" (10GB) of system ram alloted. Sadly it doesn't seem to make any difference. my internet connection is not the problem I have 175mb/s and routinely download steam games at 23MB/s. Also my system is not the problem as I have 16 threads of 4.1ghz Ryzen rockin! Also Hard Drive is not the problem as I have around .5TB of 2.3GB/s NVME available lol... Please help, I can't let it sit here for the next week grinding.
