 Changes / Improvements / Optimizations:
 General | DietPi RPi kernel: Updated to 4.9.62.
+DietPi-Config | Tools > Benchmarks: Added ability to benchmark CPU performance using sysbench: https://github.com/Fourdee/DietPi/issues/1253#issuecomment-346441545
 DietPi-Config | Time sync modes: NTP is now uninstalled when SystemD timedatectl is enabled. Reinstalled on demand. Timedatectl pool servers are now also set: https://github.com/Fourdee/DietPi/issues/1208#issuecomment-343762480
 DietPi-Software | APT log: Moved to /etc/dietpi/logs/dietpi-software_apt.log, to prevent RAMlog clearing log during automated installations.
 DietPi-Software | MPD (Stretch): Install updated to 0.20.11. Also supports native DSD playback (thanks to @sudeep and PJotr), when "Native" output freq/bit is set: https://github.com/Fourdee/DietPi/issues/1236
