No, and that doesn't say anything about latency.
There are quite a few generic tuning knobs (buffer and ring sizes,
interrupt moderation and affinity). However, many vendors of
high-performance NICs, including Solarflare, provide a performance
tuning guide as part of their documentation, which can include
hardware-specific advice.

Not speaking for my employer; that's the marketing department's job.
They asked us to note that Solarflare product names are trademarked.
