This release is fully suitable as a replacement for LinuxThreads by either a single user or group or an entire distribution. In this release, the primary focus was performance. Significant performance and scalability enhance- ments have been made to this release making it the fastest and most scalable POSIX compliant threads package available on the Linux platform. In this release, performance and scalability were the key focus of NGPT developers.? Performance and scalability were improved to the point where NGPT bests both LinuxThreads and the new NPTL threading package in benchmarks.? No changes were made to the kernel patches and thanks to the NPTL effort, all changes required to run NGPT on the latest 2.5.x kernels are already included. Performance and scalability were measured using a benchmark program developed by Sun Microsystems to "prove" that a 1:1 threading model is better than the M:N threading model.? As can be seen in the benchmark results NGPT is the performance and scalability leader on both a 2-way and 4-way machine running this benchmark.? The benchmark results can be found on the NGPT website. The benchmark itself can be downloaded from the Sun Microsystems site.
