Throughput/ File Transfer speed issues
My hardware:
Netgear ReadyNAS 102, running FW v6.9.5
2x WD20EFRX-68EUZNO (2 TB each, Western Digital Red) HDDs in RAID 1
Netgear GS105v5 switch
HP Elitebook with fresh, clean install of Win 1...
After remembering about the "top" command, I checked it, and it does seem that a single, continuous SMB write operation of about 15-20 MB/s is using 60-80% of the CPU.
Guess I found my problem. I just never thought that Netgear would have put in such an underpowered CPU that it could only use 20-25% (at best) of the rest of the hardware resources at any time (HDD read/write throughput and NIC throughput, both of which should be over 100 MB/s).
Does anybody have any tips for possibly freeing up some CPU resources? Would it even be possible to offload some network load from the CPU to the NIC?
Hi amarschilok
Yes, the RN102 and RN104 are quite underpowered. That being said, 15-20 MB/s is quite low even for those units.
I recommend that you read the excellent guide that Retired_Member made. Link below.
It contains some good tips and tweaks on how to improve performance and stability of RN100 series.
Cheers
- Also, since you are in with SSH already, what speeds do you get with a dd test?
cd into one of your shares and:
dd if=/dev/zero of=file.bin bs=4M count=250
