I tested LoadLevelInstance and Unload using an empty project. This is the only code in the level instance, and no modifications have been made to the built-in StartContent level. I tested the packages for versions 5.4 and 5.5 in this way, and then obtained LLM tables using the -LLM and -LLMCSV flags. However, the memory usage for the FMallocUnused item is inconsistent.

5.5

The graph in Figure 5.5 shows that a cumulative increase of 200M in memory (virtual memory) occurred within 400 seconds

5.4

It can be observed that the memory of the package FMallocUnsed in version 5.5 has been accumulating, whereas there is no such issue in version 5.4
