I just added a cache drive (Samsung SSD 840 EVO 120GB) to my N40L server and while the reads speeds are what I expected, maxing out my gigabit lan, write speed to the cache drive is only about 50MB/s.
I can write to the array at close to 40Mb/s, so was expecting more.
Write cache in ON in the bios, tried the tweak below from another post and it's the same, anything more I can try?
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold & logger Go Script - ondemand up_threshold set to 50
echo 50 > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor & logger Go Script - ondemand sampling_down_factor set to 50
Thanks
