Bug Description
'show status' seems to take involve non-trivial number of mutexes in something like 'show status like "%.."', also rather than a hash, it is an array, so each show status like that requires a O(n) traversal of the status vars array, so executing it even once per second as part of status check is not inexpensive.
So, it would be better to have a cheaper solution, something with an embedded library like libmicrohttpd (https:/
So, not a bug, more of a feature request.
