Zero-copy delivers. Some benchmarks from a user-space network implementation:
Zero-copy 115Mbyte/s 6% CPU Single-copy 82Mbyte/s 97% CPU
- Alteon ACEnic Tigon-2 PCI - 400MHz Pentium II (single processor) - BX chipset - 64Mb main memory - 512k L2 cache
I don't very much is actually _done_ with that data though.
