Ugh. Polling? You better have serious throughput to justify that....

- vardump 11y agoYes, polling. If kernel gets involved, we're talking about microseconds.
- rdtsc 11y ago> You better have serious throughput to justify that.... It is often about latency not just throughput. Although sometimes they go hand in hand. For example you can achieve pretty high throughput if you take the whole network stack outside the kernel and talk directly to the network card. http://www.intel.com/content/dam/www/public/us/en/documents/presentation/dpdk-packet-processing-ia-overview-presentation.pdf http://www.intel.com/content/dam/www/public/us/en/documents/... But I've seen this spin polling done when latency needed to be optimized.
