Ten of them are VPS in different datacenters, 1GB ram mostly on Ubuntu 16.04 few on 14.04, one is a physical machine at my home (and apparently has the worst performance of all of them) although has 8GB ram it also does some backup tasks.\r\nEach chunk server is running a metalogger too.\r\nthe master server is another VPS 2GB ram. I know it's too little but it should fit a few GB for testing.\r\nmy replication goal is EC 10_4\r\n\r\nThe lizardfs is mounted on the home chunkserver with fuse.\r\nI tried to push some data to the locally mounted mfs with rclone, with multiple transfers as well as with single.\r\nThe speeds start with few around 4 MByte/s, It's not much but plenty for my needs.\r\nUnfortunately in a few minutes always goes dow to around 300kBytes and this is very bad.\r\n\r\nI am trying to read the information in the cgi frontend to find the bottleneck(s) but without luck\r\n\r\nAny suggestions? or is it completely caused by the setup I've chosen?\r\nBy comparison, tahoe-lafs that is regarded as slow, in the same setup achieves around 1MByte sustainable transfers (with multiple threads)\r\n\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/lizardfs/lizardfs/issues/comments/419539319","html_url":"https://github.com/lizardfs/lizardfs/issues/760#issuecomment-419539319","issue_url":"https://api.github.com/repos/lizardfs/lizardfs/issues/760","id":419539319,"node_id":"MDEyOklzc3VlQ29tbWVudDQxOTUzOTMxOQ==","user":{"login":"eleaner","id":5169203,"node_id":"MDQ6VXNlcjUxNjkyMDM=","avatar_url":"https://avatars3.githubusercontent.com/u/5169203?v=4","gravatar_id":"","url":"https://api.github.com/users/eleaner","html_url":"https://github.com/eleaner","followers_url":"https://api.github.com/users/eleaner/followers","following_url":"https://api.github.com/users/eleaner/following{/other_user}","gists_url":"https://api.github.com/users/eleaner/gists{/gist_id}","starred_url":"https://api.github.com/users/eleaner/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/eleaner/subscriptions","organizations_url":"https://api.github.com/users/eleaner/orgs","repos_url":"https://api.github.com/users/eleaner/repos","events_url":"https://api.github.com/users/eleaner/events{/privacy}","received_events_url":"https://api.github.com/users/eleaner/received_events","type":"User","site_admin":false},"created_at":"2018-09-07T19:18:40Z","updated_at":"2018-09-07T19:18:40Z","author_association":"NONE","body":"Thank you Nathan\r\nyou are right, I have to adjust the goal.
