Have a look at the tool sysprof. This is a statistical sampling profiler
that can show you a call tree with percentages of CPU consumption. Thee
are also other sampling profilers

I don't know if it's related, but I experienced a similar problem a few
years ago.
It's a console dll written in Freepascal and compiled for Win64 and
Linux (Ubuntu). It uses several threads and uses CheckSynchronize to
make calls in the main thread.
The dll is loaded and used by a 4gl

So I have this service application which is ported from a Windows Delphi 2007
TService app to a regular command line program for use in Linux.
It runs on a RaspberryPi3B+
Normally it sits idle doing nothing but waiting for a client to connect via TCP
