My gut feeling agrees with yours, but I do not think the frequency at which write() is called should be the primary factor when you decide to make its wrapper inlined. Once you call write(2), you will hit either the disk or the network doing I/O, and at that point I'd expect that the cost of making an extra layer of wrapper call would be lost in the noise. I'd worry a lot more about from how many callsites write() is called---by inlining the extra code that is run only when the underlying write(2) returns an error to many callsites, we would make the program as a whole bigger, and as the result other code needs to be evicted out of the instruction cache, which also would hurt performance. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
