"Old and slow" refers to the number of system calls needed in the old-style getcwd(). The one in libc calls one system call, which grabs the path right out of the vnode for the current directory. The kernel does all the work of tracking _a_ path for every vnode (which for remote filesystems requires more work than for local ones, but still).
