[Boost-users] random numbers

I am considering to use boost.random library but have a problem with efficiency.
I have a class which provides two public methods:
double exponential(double mean)
and
double getUniform(double min, double max)
The implementation I have using boost.random is inefficient and I need some
advice in order to improve it.
In both the above methods I create a variate_generator object with a 
mersenne_twister generator
and the appropriate distribution. The problem is that the methods are called 
often which leads to
creation and destruction of the variate_generator and the distribution object.
I can not store those objects as member variables because the parameters mean in 
exponential
and (min, max) in getUniform varies

Thanks in advanced
