This causes normal performance of 10ms/tick (with all pipes in loaded chunks) to become 80ms/tick when the player moves away from the pipes.\r\n\r\nMy testing showed that removing sponge removes the issue, and using sponge with no sponge-mods still has the issue.\r\nEDIT: JvisualVM snapshots are available in the above link in [this](https://github.com/BuildCraft/BuildCraft/issues/3458#issuecomment-262496815) comment showing with+without SpongeForge, and with pipes in loaded+unloaded chunks.\r\n\r\nJava: openjdk version \"1.8.0_111\"\r\nForge: forge-1.8.9-11.15.1.1890-1.8.9-universal.jar\r\nSpongeForge: spongeforge-1.8.9-1890-4.2.0-BETA-1762.jar\r\nBuildcraft: buildcraft-7.2.7.jar"},"comment":{"url":"https://api.github.com/repos/SpongePowered/SpongeForge/issues/comments/263177214","html_url":"https://github.com/SpongePowered/SpongeForge/issues/1057#issuecomment-263177214","issue_url":"https://api.github.com/repos/SpongePowered/SpongeForge/issues/1057","id":263177214,"user":{"login":"zmaile","id":7214809,"avatar_url":"https://avatars.githubusercontent.com/u/7214809?v=3","gravatar_id":"","url":"https://api.github.com/users/zmaile","html_url":"https://github.com/zmaile","followers_url":"https://api.github.com/users/zmaile/followers","following_url":"https://api.github.com/users/zmaile/following{/other_user}","gists_url":"https://api.github.com/users/zmaile/gists{/gist_id}","starred_url":"https://api.github.com/users/zmaile/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/zmaile/subscriptions","organizations_url":"https://api.github.com/users/zmaile/orgs","repos_url":"https://api.github.com/users/zmaile/repos","events_url":"https://api.github.com/users/zmaile/events{/privacy}","received_events_url":"https://api.github.com/users/zmaile/received_events","type":"User","site_admin":false},"created_at":"2016-11-28T03:43:54Z","updated_at":"2016-11-28T03:43:54Z","body":"@bloodmc okay, no worries.
