texte = Webcat obviously uses thread to some extent, since we have the [spawn] context. Therefore, even if a program isn't programmed with SMP in mind, as long as the OS sees multiple CPUs, it'll pop different threads onto any available CPU. Therefore, you will see speed increases with webcat with multiple CPUs. Now, this logic holds true if you're using a lot of [spawns]. I would think that webcat uses threads throughout it's entire parsing and processing, but THAT can only be answered from the source...So, I'll have to go with Tim Allen on this one: More power, ruff ruff... -HowardOn Tue, 28 Mar 2000, Kevin Lippert wrote:> Our client wants to buy a dedicated machine to host their Webcatalog > application, and is letting us write the [dream] hardware spec.
