different speed of ODE benchmark with and without MATLAB gui

When I ran matlab benchmark on Linux at MATLAB GUI and at MATLAB command line (without gui) I get the different speed of ODE benchmark:

MATLAB GUI:

time_gui = bench(50);time_meam = mean(time_gui,1)

0.0824    0.1204    *0.0489*    0.0871    0.4029    0.4236

MATLAB cmdline:

time_cmd = bench(50);time_meam = mean(time_cmd,1)

0.0829    0.1214    *0.0142*    0.0948    0.3838    0.4166

Why is ODE (only!!!) benchmark 4x slower at MATLAB with GUI than at MATLAB without GUI (3rd number) at averaged benchmark results?

When you say "GUI" or "cmdline", are you referring to running with the desktop or -nodesktop ?

[Michal]

Situation getting be more complicated...

When I run MATLAB by desktop launcher:

[Desktop Entry]
Version=1.0
Type=Application
Terminal=true
Exec=/usr/local/MATLAB/R2018a/bin/matlab -desktop
Name=MATLAB
Icon=/home/x/.local/share/icons/matlab.png
Categories=Development;Math;Science
Comment=Scientific computing environment
StartupNotify=true
Path=/home/x/Documents/MATLAB

I observed ~4x slow down of ODE benchmark compare to the following two cases:

$ matlab -desktop

or

$ matlab -nodesktop

from command line (terminal)

For these two cmdline (terminal) commands ODE benchmark performs significantly faster.

This also happens to me. The nodesktop test for the ODE is faster.
