uploading to NAS over gigabit LAN speeds good?
I am uploading from my laptop to the RadyNas Ultra 4 plus. Connected on the Wire. Netgear gigabit switch in between. I am using filezilla to upload (ssh) I am getting 1-2MB/s steady. is thi...
I Use SmartFTP and have done for years (since before it went to a paid model).
Transfer rates over SmartFTP are comparable to transfers over Windows Explorer, and it supports all the modes your ever likely to need to connect to your NAS (FTP, SFTP, SSH, etc).
Flow control is enabled on my Desktop NIC (Onboard Realtek 8111D) and jumbo frames set to 9k (MTU works out to 8147 - 8119 plus 28 bytes for headers) but for this to work with the NAS, jumbo frames has to be enabled on the NAS too.
A guide on setting up / determining your correct MTU can be found here:

I ended up writing a batch file to automate the process. I also enabled the other settings I already mentioned like chimney offload, ECN, DMA, etc. With Jumbo frames disabled I get a steady throughput of about 40-50MB/Sec, with jumbo frames enabled I get 75-80MB/Sec. With a dedicated NIC with an onboard processing chip I could probably expect more still, but I think Realtek chips use the system CPU for processing (Both audio & networking) which can limit the throughput depending on the CPU loading at the time.
