Terrible intranet performance

[Ophidian]

Hey all!

I'm relatively new to administering a Linux system, but using guides and forum topics I've managed to get a GoFlex Home 3TB set up pretty well. I have a Hybrid MBR and working FTP and SAMBA servers.

The issue is... when I try to transfer files using either FTP or SAMBA, I get 20-30 KB/sec. I'm really confused about this. I tried using wget on a large internet hosted file, and got about 10Mbit. *edit* I'm on a 100Mbit Ethernet connection. I've connected it straight to the win 8 box which has Gbit Ethernet, but the same results. Prior to modding the GFH, I used samba and got 50 MB/sec.

Any thoughts? I realize I may have to come back with some config info. I thank you for your patience... I'm so close to having a good media server going.

Cheers!

run top/htop while transferring data to see if CPU is busy with something else. what filesystem did you format the partition where you are transferring the data from/to. Would be nice to see your smb.conf as well.

Thank you very much for the fast response. I loaded htop, and ran it while transferring a large file. Curious, I'm get 470-500KiB/sec now. Still short of what I should get though. As I watch htop, the cpu useage for proftpd spikes and goes low frequently. I don't know if this is normal. *edit* Oops, I forgot to mention the file systems. I have 3 partitions on the drive, 20 gig ext3 for ALARM, 1 gig swap, and remainder as EXT4. I'm transferring from a Win8 box using NTFS.

Back to 27 KiB/sec. Sigh.

[pepedog]

Bad cable?

[Ophidian]

If I have some time tonight I might try switching the cable and/or reinstalling ALARM. I wonder if I installed incorrectly?

[Ophidian]

A quick update for any who are interested:

I've restored the stock bootloader in flash, wondering if my Arch Linux is messing things up. Still slow transfer.

Next, I alter some settings in the Win8 box, disable flow control and set jumbo frames to 4K. I set MTU to 4000 in the GFH. Now I'm getting 22 MB/s, with 91% CPU use in the GFH! Reading back, I get 27MB/s.

I did see higher before I started goofing with the GFH, but this is clearly a step in the right direction. The media partition has been reformatted to ext3, as the stock OS doesn't like ext4. Using the mke2fs and a swap partition, I can format large no problem.

I still don't know what caused the large drop in net performance, though.

[moonman]

flow control was the only setting you needed to change. Change mtu and jumbo back to stock as they probably reduce theoughput in this case. Everything else seems right.
