Abstract
A first and second thread-local counter is allocated to a first and second thread respectively, where the first thread-local counter is updatable only by or on behalf of the first thread and the second thread-local counter is updatable only by or on behalf of the second thread. The first and second thread-local counter are updated and the updated values are communicated to a central process. The central process updates a single counter in a central database by a value equal to the sum of the updated counter values.
