hi!
here is my problem
i am multithreading my program with boost but i don't get what i expect, and i can't understand why!
i just run one thread and wait for it, and the fps are divide by 3. basically with no thread i have 30fps, and with 1 thread i have 10fps. :cursing: here is the code:

boost::thread_group forces_threads;

forces_threads.create_thread(boost::bind(&ElasticRods::computeBendingForces,this,edges,kb,edges_initial));

forces_threads.join_all();

i use thread_group because i want to run 7 thread but it is already too slow!
do you have an idea of why this is so slow?
thank you for your help! :)

You haven't given us a lot of code to work with, here.
