So what's the equivalent replacement for it The application has a heap of 8gb and creates a lot of short living objects I noticed that it often paused for some seconds to do garbage collection Do you load many different classes dynamically Then you could maybe define a free ratio on the metaspace so that always enough space for new classes is available and no resizing will be needed in critical situations. Unfortunately (and in spite of the disclaimers in the documentation), many developers decide they know better than the jvm when to collect memory and introduce exactly this type of issue This is the option that can be used for the case mentioned in the question Checked on oracle jdk and openjdk java. *.h or *.hpp for your class definitions what is the difference between.cc and.cpp file suffix I used to think that it used to be that .h files are header files for c and c.
