Steps to reproduce

1. When there are many deployed ECMs and the concurrency is high, an exception may be thrown: Comparison method violates its general contract!
2. The comparison method provided by the code is: when memory, CPU, and the number of instances are all large, return -1; when memory, CPU, and the number of instances are all equal, return 0; in all other cases, return 1.
3. There may be situations where, when the memory of A is larger than that of B, and the CPU of B is larger than that of A, the comparison between A and B will always return 1.

Expected behavior

Modify the rules of the comparator to prevent violating the general contract of the comparator.
