Answer from AI

If garbage collector (GC) pauses have increased 20-fold and the application has started to slow down, you should:

  • Analyze what has changed in the load or code that caused the increase in allocations.
  • Use a memory profiler to find leaks or excessive object creation.
  • Optimize the code by reducing the number of temporary objects.
  • Consider adjusting GC parameters (such as heap size, GC type) to reduce pauses.
  • If necessary, switch to a more suitable garbage collection algorithm (e.g., G1, ZGC in Java).

Example: if new objects are created in a loop without necessity, it is worth rewriting the logic to reuse objects or use primitives.
