This partially reverts commit 5ab6db26079c5b51bc920392eb3a75b4242a2347. The change of argument --threads N doesn't just change output, it changes the mode of operation. With --threads 0, the benchmark runs wholly in the main thread. With --threads 1, it starts 1 worker thread, which does the work, and the main thread measures how long it takes to complete.

Mapnik is an open source toolkit for developing mapping applications. At the core is a C++ shared library providing algorithms and patterns for spatial data access and visualization.
Mapnik is basically a collection of geographic objects like maps, layers, datasources, features, and geometries. The library doesn't rely on any OS specific "windowing systems" and it can be deployed to any server environment. It is intended to play fair in a multi-threaded environment and is aimed primarily, but not exclusively, at web-based development.
For further information see http://mapnik.org and also our wiki documentation.
