SAMBA + EXT4 only 6mb/s?

[fox1986]

after several newbie struggles, I got my Pogoplug V2 E02 running as a SAMBA Nas Server.
Configuration is as follows:

1. Lower back port USB: 2 GB USB Stick EXT3 running Arch Linux
2. Upper pack port USB: 2 TB Western Digital USB 3.0 Harddrive with EXT4

Samba is working without problems, but my harddisk can only read and write with max 4-7 mb/s.
The filesystem of the mounted disk is EXT4, connected via Gig-Bit capable Linksys Router E2500.
I access via Windows 8 over WLAN-n (I used to have 30 Mbits on internet-speedtest via that connection
so it should be far better than 4-7mb/s)

I tested writing speeds with hdparm on my 2 TB disk: about 29 Mb/s. But when I try to read and write
files from Windows, I never get over 7mb/s. I know other people here reach easyly more than 20mb/s.
What is wrong with my config?

Are you confusing Mb (megabit) with MB (megabyte) by any chance?

[moonman]

Yeah 30mbit/s on speedtest is 3.75 mByte/s

bps = bit/s
Bps = Byte/s
Byte = 8bit
Always

Wireless wont give you over 15 mB/s
(300Mbit/s (in the best case scenario) is half duplex = 150Mbit/s = 18.75 MByte/s - some overhead =15 MB/s?)
and then if you are connected @ 150Mbit/s it will be half that - 7.5Mb/s which is what you get?

Avoid wireless if you want good throughput.

I get about 13 mB/s @300Mbit/s connection rate so it will depend

[fox1986]

Oh sorry, you are right of course. Just mixed up mbit and mb/s (just too hot here)

But anyways: I run a WLAN network in n-Standard with dual-channel support, so I think that I should reach a higher transfer rate than 6mb/s, since n-Wlan should support up to 37mb/s. I ran my SAMBA with NTFs partition before and suprisingly it was 6mb/s too. So I guess there must be another limiting factor slowing down read/write speeds from/to Windows -> Pogoplug. Ideas?

Maybe someone has a working smb.conf for me?

You're hitting the CDMA limits of 802.11g period. Even with 802.11n with no other devices or noise, you're going to max at approximately 12 at max, in best of the best conditions.

[fox1986]

I somehow doubt its a wifi problem. I only get 56mbit out of 300mbit possible WLAN bandwith. I know that this should be at least twice as fast. The pogoplugs cpu is out of the game too. Its not even at 27% while copying data.

Tested now via Ethernet LAN: its 6-8 Mb/s, so same speed as wifi. It must be something different

[moonman]

All wireless is half duplex, so divide whatever signaling rate you see by 2, that is your maximum theoretical throughput (you will likely never see, rather substitute several megabits from that as well). With ethernet the pogo is gigabit, your router IS NOT. E2500 only has has fast-ethernet switch.

Fast-ethernet = 100 mbit/s
Gigabit-ethernet = 1000 mbit/s

also disable flow control on your pc to get upto 12-13 mB/s.

I tried to speed-test mine too, but then I discovered that my laptop doesn't have gigabit ethernet. D'oh!

[moonman]

Even if your laptop did, you would still be limited to 100 by the router

Except that I was connecting the two directly with a crossover cable. A moot point, though ... just sayin'.
