Hi all,
I have the following problem: When I try to open a Simulink model with an UDP receive or send block (from the Instrument Control Toolbox) for the first time after starting Simulink, I have to wait over 30 minutes until the program show ready. After this first launch, I can work with the model without any problems. The problem still persists after reinstalling Matlab and Simulink. During the startup time, I can see in the task manager that Matlab is using 35 % of the CPU power. There are two processes from type "Java Chromium Embedded Framework (JCEF) Helper" and two from type "Matlab 2020a". I think it is a problem with the "Instrumental Control Toolbox" because I only have this problem when I use blocks from it.
Does someone else also have this problem and how can it be solved?

I have got the same problem after simulation. Since matlab 2020 requires more than 8GB of RAM, the problem must be associated with the RAM. I hope after increasing the RAM of your system, the problem will automatically dissolved

Hello and thanks for the answers but they don't solve my problem. I am now using Matlab 2020b on a computer with 16 GB of RAM, I7-7500U CPU and still the same problem. A simple model with just a UDP receive block takes 3 minutes to load (when I open it for the first time, if I close the model and open it again, it takes half as long). Java is up to date and I don't have prescan installed.
So, I think the best solution to the problem is to use udp blocks from other libraries (e.g. DSP toolbox). The same Model with a UDP receive block from the DSP toolbox takes less than a second to load on my system.

I have the same problem, usually triggered by plotting within a live script .mlx

R2022a have the same issue... MATLAB Takes up too much memory

I met the same problem, matlab live scrip .mlx suddently runs very very slow. Open task manager, many processes of Jave Chromium Embedded Framework (JCEF) Helper are listed.
Any suggetions to resovle this problem? Thanks.

I have experienced the same problem with Matlab 2021a
Experimenting with toolbox UMAP, matlab remains iddle as busy (in fact it is "frozen"... and I have to terminate it from task manager) and at the same time the task manager indicates several JCEF Helper processing runnings...
how can resolve this technical issue???
Windows 10 , 16GB Ram...
