If you do, please do not hesitate to contact QNAP support or open a new discussion, because in real life operations, other known facts could also cause slow performance, including bad blocks on the hard drives, very little free space left on the disk volume, or fragmented data. .

I perform a quick test with a couple network configuration (single eth port and link aggregation) and a 4GB file, as before transfer from the QNAP to one of my servers starts well over 120MB/s and after 10/15 sec drops to 90,80,... all the way down to 15/16 MB/s.
Memory usage stays stable at 300+MB, CPU utilization seems to fluctuate over 95%. Disk utilization is around 74%.
Hoping to read more "first impressions" of the new firmware.
The Kernel is based on a cetainl level (as shown), there are many QNAP enhacements and updates in place - making any version number comparisons useless.as321 wrote:Could someone verify what kernel version Qnap uses for the formware version 3.7.1 please ?

for a simple mind: QNAP does update the Kernel without changing the version number - that one is kept on the original base, why ever.as321 wrote:Please read your response and see if it makes any sense to you - it doesn't to me.
Ok, for the boy scout: QNAP has updated some Kernel parts - this does not make an all-new kenrel, so the base version number is still the same - and you can NOT compare it to a common Linux distribution Kernel version.as321 wrote:Qnap themselves acknowledged that the kernel update will be needed, I know the kernel needs to be updated..., forgive me but what made you think you are talking to a boy scout ?
