Of course we know about splice(). You can find some mentions of it in the mailing list archive since 2006. The problem with this syscall is that it's not easy to implement, while the performance benefits are questionable (AFAIK not all network cards work well with splice()) and use cases are limited. It only can be useful for proxying big amounts of data without any processing. But if you need compression, or TLS, or SSI, or even some simple substitution, then splice() cannot be used. wbr, Valentin V.
