Linux threads how?

Question

linux

I create a flow

int result = pthread_create(&thread1, 0, new_connection,s);

Why does an empty stream take up 10MB of memory?

Answer 1

Maybe under the stack?

Answer 2

Maybe it's not real memory, but shared memory? Create N / 10 threads, where N is the number of megabytes of memory installed in the computer.

Answer 3

This is shared. It's hard to keep track of...
Experiment for - fill some global array with a lot of data and see if the memory grows under the thread.
Just in case, look at the stack size through pthread_attr_getstacksize , it may cost a minimum stack of 10 meters.
