Hello!
I have the following problem: "md5sum: command not found"
Anyway Im using a different approach, here is another way to check your CPU singlecore speed:
time $(i=0; while (( i < 9999999 )); do (( i ++ )); done)
Uses only one CPU core
Very simple, no preparations needed
The lower the output value is the better
I compared various setups using this command, here are my results:
My old Synology DS214
real 8m52.640s
user 8m40.240s
sys 0m0.070s
XPEnology inside VMware virtual machine running on Windows 7, CPU: Intel i7 2700K @ 4.2Ghz
real 0m32.051s
user 0m32.018s
sys 0m0.032s
XPEnology on ASROCK J4205-ITX
C1E: disabled, SpeedtStep: disabled, PowerMode: Sport
real 1m55.765s user 1m55.794s
sys 0m0.003s
XPEnology on ASROCK J4205-ITX
C1E: disabled, SpeedtStep: ENABLED, PowerMode: Sport real 1m11.878s user 1m11.890s
sys 0m0.010s
I wanted to find out is SpeedStep working or not. Now it is very clear to me that enabling SpeedStep is a must on my J4205 board, improved single core speed by +64%. I really feel its effect on the Web GUI and on photo conversions.
