I think so, in some environments anyway. If you have a server tuned for high throughput accross large bandwidth-delay product links then you have the general problem of equal-priority threads sitting around with quite a lot of large impending writes.

Doesn't sendfile (and others) help in that case? Also RAM is cheap, bandwidth isn't :)

Oh if you can use sendfile, you use it sure, and whether its used async or not isn't going to make a big deal, all of the benefits are the zero copy, the DMA, the TOE, and so on. That's not even a consideration, async is really for dynamic content, proxies, and other non-sendfile content.
