From: Hao Xu <howeyxu@xxxxxxxxxxx> splice from pipe to pipe is a trivial case, and we can support nonblock try for it easily. splice depends on iowq at all which is slow. Let's build a fast submission path for it by supporting nonblock. Wrote a simple test to test time spent of splicing from pipe to pipe: Did 50 times test for each, ignore the highest and lowest number, calculate the average number: before patchset: 119.85 usec with patchset: 29.5 usec
Hi Al, Any comments on this one? Regards, Hao
