We used uname at some point but then I did some profiling and sysctl turned out to be faster. If the reverse is true now I can certainly look into changing this but the evidence and ideally has to be there. The simplicity of the uname code should mean that it's faster. In a year or two I'll remove the test anyway. By then there will likely not be any UP kernels on reasonable machines anymore and I can drop all the conditional code. -- â Ulrich Drepper â Red Hat, Inc. â 444 Castro St â Mountain View, CA â
