It's not clear if you used sbin symlinks in tests, no script attached. It's VOP_READLINK overhead we should care about. All entries (incl negative cache) will be cached by VFS under bin/. I presume difference to be negligible and support the change. sbin/something lookup: vp0 = VOP_LOOKUP(sbin) (may be cached) VOP_READLINK(vp0) vp1 = VOP_LOOKUP(bin) (may be cached) vp2 = VOP_LOOKUP(something) (may be cached) > > Observations: > - Indeed, the running time increases when the binary to be executed is > in a directory that is placed farther to the end of $PATH. > - Redundant directories in $PATH do cause some overhead. > - When we merge sbin with bin and the user properly removes sbin from > his/her PATH variable, things get slightly faster than they used to > be. > - When the user forgets to do so, the results are slightly worse than > before. > > Of course, this was just a quick way of testing things.
