I have been working with around 50 full-nodes up to this day and the longest it took for any of it to fully sync was about two days. I have been running NEO on the same class server and after 20hrs I am at block 210338, while https://neoexplorer.co/ shows me the highest one is at 1828385. Dividing this value gives me the number of ~9 days needed for sync. If I assume the NEO behaves the same other cryptos, and the most 10-20% recent ones will sync slower I can probably assume full sync will be completed in 14 days. This does not look normal. Why is it so slow? Is there any way to make it faster?\r\n\r\nMy specs:\r\n- Dedicated server\r\n- Ubuntu 16.04 x64\r\n- 64 GB RAM\r\n- SSD\r\n- Network 100 Mbps\r\n- NEO ver 2.6.0"},"comment":{"url":"https://api.github.com/repos/neo-project/neo-cli/issues/comments/363051947","html_url":"https://github.com/neo-project/neo-cli/issues/100#issuecomment-363051947","issue_url":"https://api.github.com/repos/neo-project/neo-cli/issues/100","id":363051947,"user":{"login":"PeterLinX","id":18521923,"avatar_url":"https://avatars2.githubusercontent.com/u/18521923?v=4","gravatar_id":"","url":"https://api.github.com/users/PeterLinX","html_url":"https://github.com/PeterLinX","followers_url":"https://api.github.com/users/PeterLinX/followers","following_url":"https://api.github.com/users/PeterLinX/following{/other_user}","gists_url":"https://api.github.com/users/PeterLinX/gists{/gist_id}","starred_url":"https://api.github.com/users/PeterLinX/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/PeterLinX/subscriptions","organizations_url":"https://api.github.com/users/PeterLinX/orgs","repos_url":"https://api.github.com/users/PeterLinX/repos","events_url":"https://api.github.com/users/PeterLinX/events{/privacy}","received_events_url":"https://api.github.com/users/PeterLinX/received_events","type":"User","site_admin":false},"created_at":"2018-02-05T11:02:17Z","updated_at":"2018-02-05T11:02:17Z","author_association":"MEMBER","body":"@khelle if you think it's not safe, you need to download it all over and it really takes time. Because you have almost 2000000 blocks to sync with. Also, as you know, the speed of syncing data depends on p2p network, if your server have very few nodes connection then your sync process will slow down big time."}}
