- Without readdir plus, an unmodified 2.6.38 kernel takes longer to remove a large directory than the other kernels
- Using readdir plus removes large directories faster than using a simple readdir.
- Kernels perform the same without readdir plus
- With readdir plus enabled, the kernels take about the same amount of time to remove the directory.
- The command takes about the same amount of kernel time for each tested kernel.
- Using readdir plus decreases the kernel time needed to complete the command
