Can multithreading speed up memory allocation?

Question

I\'m working with an 8 core processor, and am using Boost threads to run a large program. Logically, the program can be split into groups, where each group is run by a threa

Answer 1

Roll your own non-multi-threaded new memory allocator a distinct copy of which each thread has.

(you can override new and delete)

So it's allocating in large chunks that it works through and doesn't need any locking as each is owned by a single thread.

limit your threads to the number of cores you have available.
