I'm having a weird issue with performance which manifests as soon as I look at a dialling device - the server CPU utilisation goes from ~10% to ~90% and stays there until the server is restarted. Memory also goes from ~50% to ~85%. I don't need to use the dialling device, just looking at the interface is enough to trigger it. The handheld teleporter doesn't cause any problems. I have a few dimensions of my own but none of them have chunk loaders in. The pack's default dimension (dimension 2) does seem to have some from what I can see.\r\n\r\nI've tried using [TickProfiler](https://github.com/nallar/TickProfiler), which gave me some results I don't entirely trust:\r\n![2016-12-18_23 24 33](https://cloud.githubusercontent.com/assets/1374274/21297497/7166fa4c-c579-11e6-8580-8fd7ca1126d4.png)\r\n![2016-12-18_23 24 56](https://cloud.githubusercontent.com/assets/1374274/21297498/72a4e342-c579-11e6-89cc-eb51e3af294a.png)\r\nespecially since none of the chunks it mentions are anywhere near my base, and I'm the only one logged in...\r\n\r\nSo I suppose my questions are:\r\n\r\n* Does looking at the dialling device trigger chunk loaders in other dimensions to come online, or do something else that could use a vast amount of CPU?\r\n* Is there a better diagnostic tool I could use, or something? I'm fairly incompetent as a server admin."}}
