I created user-defined system images of some packages.

I want to preload packages using -J switch. However, I have a problem.

For example, I did the following using three system images.

**julia -J sysimage1.so -J sysimage2.so -J sysimage3.so**

Julia loads the first and the last system images, but not the second one, sysimage2.so.

The size of each system image is between 140MB and 250MB.

Can Julia load only two system images or is there a limit on the total size of all system images to be loaded?

Or am I doing it the wrong way?

For your reference, I am using Window 10 laptop with 16GB RAM.

Did you get an answer to this? It didn’t even occur to me that it might be possible to load more than one sysimage.

Unfortunately, not. I guess I have to settle for two sys-images.
