However, this exercise demonstrated that the JVM needed significantly more memory (20%) that what is implied by its heap settings, even for nearly the simplest possible Java webapp. This issue generally will happen if your project is really big or wrongly designed. Another big problem is the dreaded occurrence of memory leaks. We can bump that up using the max_old_space_size flag. Ensure that your application runs only on hosts with adequate resources. containers from using any swap. performance penalty for applications that swap memory to disk often. to your account.
