Does the packet filter vs routing performance thing apply also on Linux, would doing this with netfilter add perf overhead and do people run Linux without netfilter in high-load environments? Is using route tables instead a valid pattern that should be applied also more widely?
- cperciva 7y agoDoes the packet filter vs routing performance thing apply also on Linux I haven't looked at the Linux kernel code, but keeping routes cached per-flow is a trivial optimization; I'd be shocked if they weren't using it.
