Even if it were, on any sanely designed OS, there really isn't any extra expense for a process over a thread. > Moreover, to get at best a small performance gain you pay a > huge cost by sacrificing memory protection within the threaded > process. Threading most certainly shouldn't be done in some attempt to improve performance over a multi-process model. It should be done because it fits the algorithm better. If the execution contexts don't need to share data and can communicate in a simple manner, then processes probably make more sense. If the contexts need to operate jointly on complex shared data, then threads are usually easier. -- Grant Edwards grante Yow!
