| Arta | Does anyone know of a way (functional under >=win2k) to find the size of the processor's L2 cache? | January 25, 2004, 4:18 PM |
| Skywing | You can use cpuid with level=2 to get it from P4s... | January 25, 2004, 4:39 PM |

| Adron | You could make a loop doing an operation on a dataset of a certain size. Increase size step by step and measure performance. When performance drops more than linearly, you've hit the cache size. | January 26, 2004, 4:53 PM |
