[Boost-users] serialized memory allocation using boost::pool

4 May 2005

      Hi,

I am trying to improve the performance of a std::list instance in a 
multi-thread application using boost::pool, but the syncronization 
overhead is killing me.

The point is that all access to my std::list are serialized, so I would 
like my pool to not use mutexes when retrieving memory in the pool, 
which is what I suppose is happening (got evidence through valgrind).

 From the template parameters of boost pool, I think this is possible, 
but I couldn't figure out how to do this. Any tips here?

pseudo code:

struct X;
std::list<X *, boost::fast_pool_allocator<X *> > l;

lock();
//fill l with 1000 X * instances
unlock();

lock();
for (uint32 i = 0; i < 1000; ++i)
{
	X *x = l.front();
	l.erase(l.begin());
	l.push_back(x);
}
unlock();

Thanks in advance,
