Comment (by anonymous):

 I was recently hit by this problem. In my application, if I use
 boost::object_pool, it runs 12 seconds. Through profiling, I know it was
 due to find_prev(). So I replaced it with boost:pool. Now it finishes in 1
 second.

 I was wondering if we can simply do the following change to fix the
 problem?

     void free BOOST_PREVENT_MACRO_SUBSTITUTION(element_type * const chunk)
     { //...
       store().ordered_free(chunk);
     }
 to

     void free BOOST_PREVENT_MACRO_SUBSTITUTION(element_type * const chunk)
     { //...
       store().free(chunk);
     }
