The article suggests interrupt load is the major issue, although doesn't really say enough to inform us. A 12.5ms buffer means potentially just 80 wakeups/sec.

The article suggests interrupt load is the major issue, although doesn't really say enough to inform us. A 12.5ms buffer means potentially just 80 wakeups/sec. They don't mention whether they use multiple hardware queues or if all interrupts hit a single core.
I'd also be interested to know if polling mode was tested with any of the cards, and why it didn't work out
- eastdakota 13y agoWe use multiple hardware queues. Some details in this old blog post: http://blog.cloudflare.com/how-the-cloudflare-team-got-into-bondage-its http://blog.cloudflare.com/how-the-cloudflare-team-got-into-... We're continuing to experiment with polling-based network queues.
