Why do so many Java processes run when a Java program runs?
Created May 4, 2012
Nathan Meyers In Linux, every thread gets its
own process ID. So when you run tools like
ps or top while using Java,
you see a separate entry for each thread - even
though you are only running one program.
One clue that these are all threads of the same program is the memory size - it is identical for all the threads because they are all using the same memory.
