      "description": "I run a server on a linux ubuntu server and from what I can tell, it doesn't appear to be using the majority of what the server hardware is capable of. Ram I would expect it to not use much as it isn't java, but cpu power it just kind of maxes out two threads and just kind of does nothing else. People on the server experience lag at around 5 people which is weird. I have 2 six-core xeon cpus clocked at 2.66hz, but its running as if I had 1 cpu with 1 core at 2.66hz. I assume multi threading hasn't been added but I don't know much about how this is developed. Something I did notice is that in the list of /bedrock_server processes shown in htop, some of them are using more then the two cores but that doesn't seem to be represented in how the server is running. Attached is a picture of this",

               "body": "Just to give a little more context to my duplicating this ticket into BDS-2574...\n\nAt the moment there appears to be issues with Linux performance since at least 1.14 (although there are reports from prior to that).\n\nIn your case, please note, the CPU you're using isn't ideal. While Bedrock Dedicated Server is multi-threaded in some scenarios, the main game thread is still single core sensitive. Your CPU's single core score is _very_ average because its designed for server based, multi-core workloads.\n\nHowever, you should be able to have 5 people online I would have thought without issue so I believe you're being affected by the current Linux performance issues and have duplicated into that to collate as much info as possible.\n\nIf you have any more info you think should be added to the summary in that report please let me know.\n\nIonic",
