Mediocre performance- Why?
I’m frustrated with my upload speed to my NAS. Should I be?
I’m able to upload at about 14MB/s. I was expecting 25+MB/s. Was this an unrealistic expectation? I frequently upload large files: 10GB+. Additional speed would be very useful.
Here’s what I got:
Ready NAS Duo RND 2000 -100
RAIDiator 4.1.8
XRAID
2x Western Digital 2TB drives: WD20EARS (87% free)
Gigabit connections (computer / router / NAS)
Cat6 cables (all)
Jumbo frames disabled (Win/NAS/Router)
Journaling disabled
Fast CIFS enabled
Linksys E3000 w/latest router firmware
Fast PC w/ssd
Fresh install of Win7 64
Clean, current and correct drivers for realtek integrated NIC
Below are my network errors after transferring 3GB file to the NAS:
Auto-negotiation 0
Bad packets 0
Disconnect 0
False carrier 0
Idle errors 0
Link failures 0
Receive errors 0
Symbol errors 0
VLAN tags 0
TCP Retransmits 10
Unrecovered TCP Retransmits 4
I’ve read all the related posts and various web resources I can find. I have nothing left to try.
Any help or advice would be much appreciated.

- You could try jumbo frames in the direct connect config first...
A reasonable idea. They don't always help (it is hardware dependent), it would be useful to see the potential gain before you commit to using them.dsm1212 wrote: You could try jumbo frames in the direct connect config first... - Okay:
I added a switch with jumbo support. I enabled jumbo on PC and NAS. Upload is now at 23 - 24MB/s.
This is near my original expectation. I’m happy, for now (an Ultra is likely in my future).
The assistance on this forum is impressive. Thank you.
