A very good point indeed. I overlook the hidden malloc behind the C++ new and hidden free behind delete.

Linking with libmtmalloc should more than significantly boost the performance.

Code:
/usr/sfw/bin/g++ -g -Wno-deprecated ss2.cpp -lpthread -lrt -lmtmalloc -o ss2

Yes, but it's still benchmarking nothing particularly useful.

Benchmarking multithreaded malloc/free might make sense.

If you write your objects to an mmap'd file, extending it, you never need to malloc or free. Of course, writing so the objects get reused not deleted saves that churn, in C++, JAVA or whatever OO language.
