Solving a model takes x8 longer when launched from the MATLAB Livelink than from the COMSOL GUI

I'm seeing unusually long solution times when I run my model from the Matlab livelink. From Matlab it takes around 60-100s to obtain a solution in my model. Running the same model in COMSOL GUI yields only 10s solution time. This is a big headache for me since I need to run long sweeps, whose accumulated time becomes unpractical with the long solution times from Matlab.
Since I didn't have this issue in previous versions of COMSOL, I wonder if this is a known COMSOL 5.4 bug. The effect stays the same after I restarted Matlab and my desktop.
Does anyone have an idea of what could be going on?
