Simulink stuck between initalizing and running

When I'm running a Simulink model the first time after Matlab startup, the simulations takes 15 seconds..

Then, each time I run the model it takes several minutes after the initialisation, either displaying "running t=0.00" or just "running". Then the times increments normally and it goes on the the simulation phase.

I have the same phenomenon on different models, one using Power System, one particularly large, one only using the control toolbox.

I have tried tweaking the settings, using fixed steps, variable steps, changing the tolerance without any improvements.

I've tried using sldiagnostics and the profiler, but the several minutes are missing, as if they were between the compiling and running phase.

A colleague running the same model on a computer with the same specs doesn't have the same issue.

Do you have any ideas where to look for?

It looks like I was streaming too many signals.

Deleting the archive in the SDI helps a lot too.

It happens to me as well

I was needed to delete my dashboard scope(only one signal) but it solves my problem.

Thanks
