Abstract |
We find that: (a) Our base protocol reaches almost 99.2% of the nominal aggregate throughput for up-to 2 psychical links of 1 GBit/s link rate. (b) When up-to 8 physical links are used, our protocol achieves up-to 65% of the nominal aggregate throughput. (c) The impacts of interrupts and data copies are significant, and when they are removed, protocol reaches 80% and 100% of the nominal throughput respectively. (d) With bi-directional link rates of 30 GBits/s, data copies limits the effective throughput to about 8.8 GBits/s on our systems. (e) The use of our zero-copy mechanism results in 80-90% improvement and reaches up-to 57% of the available bi-directional throughput. Finally, we believe that efficiently distributing protocol processing over multiple host CPUs emerges as the main challenge in achieving higher transfer rates on modern architectures. |
