issue will track the investigation and resolution.\r\n\r\n### Performance regression of HTTP and FTP over TCP\r\n  * This seems odd as forwarding as configured by the blog author does not include any HTTP or FTP\r\n\r\n### Increased memory consumption\r\n   * Pre-allocated connection tracking table. The size is configurable but it is at the larger end of the spectrum and is not yet adjusted to system size / total memory available. (TBD: create 1.4 issue)\r\n   * Large Cilium container images and binary sizes. This has already been partially addressed in 1.4 by reducing the binary sizes. Upcoming templating will remove the need to ship a compiler and will dramatically reduce the container image size.\r\n\r\n### Increased CPU consumption\r\n  * The benchmarking as preformed renders in some previous results and can be inaccurate but does not explain the entire result.\r\n  * The upcoming templating will help drive down CPU consumption on pod startup and also reduce the time to setup pod networking."},"comment":{"url":"https://api.github.com/repos/cilium/cilium/issues/comments/443742408","html_url":"https://github.com/cilium/cilium/issues/6351#issuecomment-443742408","issue_url":"https://api.github.com/repos/cilium/cilium/issues/6351","id":443742408,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0Mzc0MjQwOA==","user":{"login":"aanm","id":5714066,"node_id":"MDQ6VXNlcjU3MTQwNjY=","avatar_url":"https://avatars0.githubusercontent.com/u/5714066?v=4","gravatar_id":"","url":"https://api.github.com/users/aanm","html_url":"https://github.com/aanm","followers_url":"https://api.github.com/users/aanm/followers","following_url":"https://api.github.com/users/aanm/following{/other_user}","gists_url":"https://api.github.com/users/aanm/gists{/gist_id}","starred_url":"https://api.github.com/users/aanm/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/aanm/subscriptions","organizations_url":"https://api.github.com/users/aanm/orgs","repos_url":"https://api.github.com/users/aanm/repos","events_url":"https://api.github.com/users/aanm/events{/privacy}","received_events_url":"https://api.github.com/users/aanm/received_events","type":"User","site_admin":false},"created_at":"2018-12-03T15:07:43Z","updated_at":"2018-12-03T15:07:43Z","author_association":"MEMBER","body":"Autodetect mtu for VxLAN device #6368 "}}
