It seems like the “rate” for server scripts in the Developer Console keeps increasing without reason, but only sometimes. This is what it looks like after a couple of hours when the bug has happened:
The microprofiler looks the exact same as when the server started, though. Less than 3ms frame times, and the amount of labels seen in it is roughly the same.
This is on Windows 10, 64 bit.
Side note: ChatServiceRunner still takes up quite a bit of processing even when chat is disabled completely. Why?
