Hello,

I have built a simple application using App Designer - compiled into a stand-alone executable.

One tab control - 3 tabs, table + graph on each tab.

No more than 100 rows in each table - small data set (numbers only).

whenever I try to scroll up or down, I literally watch paint dry - I see the data portion painting on the screen, then I see the row names painting, after the table is painted it takes 1 second for it to become responsive
when try to switch to a new tab, it takes 4-5 seconds after the click for the new tab to start appearing, some additional 1.5 - 2 seconds for the tab to become responsive.

I run Matlab on a 8GB RAM / 2.2GHz machine, task manager shows the following usage: CPU at 5% (Matlab 1.2%), Memory at 60% (Matlab 900 MB), Disk 2% (Matlab 0 Mbps).

Did anybody ever run into a similar issue? Can anybody give me a suggestion?

Thank you

Software created with MATLAB does run very slowly，if you want to run quickly ,you had better to use C# to creat a software

Yeah. I had to deal with the same issue.

You have to update the graphic driver of your computer and your OS (old versions of Windows 10 can turn Matlab into a terrible IDE!).
Mathworks made improvements in uitable class in its 2021b release, so now it's ok.
