Is it possible to guess the amount of memory RetDec will need for decompilation?

Is there a way to guess the amount of memory retdec is going to need for decompilation?

I'm thinking of creating a web service to automate decompilation. The idea is to spin up a cloud instance with the right amount of memory, do decompilation and shut it down once decompilation is done.

To optimize costs (= decide which cloud instance to spin up) it would be good if I could know how much memory the process is going to take up.

Hi. I am afraid that there is no simple relation between static properties of the input file and the amount of memory RetDec will need to decompile it. A rule of thumb may be the bigger the file, the more memory RetDec may need, but this is generally an oversimplification. The amount of memory depends on many factors, including the number of instructions in the file, whether RetDec is able to correctly decode the instructions, detection of statically linked code, and decompilation parameters (e.g. selective decompilation may require less memory than full decompilation).

One of our long-term goals is to reduce memory requirements of RetDec (#13), but this is going to be a long run.

Ok, I figured the "the bigger the file, the more memory RetDec may need" was going to be my only option.
