Very slow Ftp-speed

I'm using ftp to upload files to BubbaTwo.
For the moment there will take about 2 and a half hour until the work finish.
The same amount of files ftp:ed to a NAS took less than 1 minute.
I alwas have that slow transmission when using ftp to BubbaTwo.
Why?
Edit:
It lookslike that the speed is only 9.2 kB/s. And that in a network with at least 10 MB/s

This is strange, did you get it solved?

I have a new Bubba 2 and have also a very slow ftp connection. I run the Bubba as a server only (no WAN connection) and access it from within my LAN.
I connect using Windows explorer to
ftp://bubba and it takes 60 seconds to log on. To change directory takes 30 seconds. Strange?

No, I havn't solved the problem.
In fact at that transmission toke 12 hours for 2500 files with a total of 98M
I also saw that the speed get down to 1.2 kB/s. Maybee it has to do with the smal amount of RAM.
I can mention that there was no other trafic to and from the Bubba.

What version of Bubba 2 software are you on? Network speeds have been reported as a bit odd for a lot of people and I fixed it by using a kernel off the unstable repo, but I don't recommend that for everyone.
Is it just ftp or is it networking in general?
Is it just slow to one host or several different hosts?

The version is 1.1.4 as I can find.
And it looks like that it is only ftp which is slow.
Download seems too have reasonable speed.

Try upgrading to 1.2.4, which is the latest version

Yes, now I havw upgraded to 1.2.4
I tested a ftp-transmission with 6 files with total of 8.3 MB
Transmissionspeed not more than 65 kB/s and toke about 2 minutes.
I feel it will run a little faster, but ....
During the transfer there was a couple of interups, the transmission halted for a while and than continued.
When I access bubba with ftp or ssh bubba respods very slowly, it takes a couple of seconds befor I get any respons.
But when I get respons with ssh it work with reasonable speed.

Strange, it seems either that your Bubba's CPU is heavily loaded for some reason, or that something is fishy with your network. For instance I have seen similar problems when I happened to connect two cables between my switch and my router, for some reason the EOL didn't seem to work and the network was practically killed due to the circulating traffic.
The fact that only FTP shows this performance is strange though. What FTP client do you use? Can you try to switch to passive mode, just to check? Is the speed constantly low, or does it start higher, to slow down later on in the transmission?

I use gFTP from my desktop.
The speed decrease.
Transmission between other hosts works with normal speed so I don't think the problem have to do with the network.
The problem have to be with bubba because the speedproblem occurs only with bubba.

Hi again,
To be able to dig deeper into this we would need to know the age and batch number of your board. This can be done in two ways, either you open the board and read the revision and label serial number, or you give me your board MAC adress and I can check in our production database. The MAC can be checked either from your router's DHCP server log (if you have any), or through one of the following options:
- reboot your bubba two and log in to the web UI as admin. Go to settings->logs and show the syslog. Copy and paste the entire contents and send to us (preferrably to
support@excito.com). While you are at it, please send the FTP log as well.
..or:
- log in with ssh, become root (su / excito) and type 'ifconfig' on the command line. Send the output to us.
Thanks again. We'll do what we can to make this work for you.
Best Regards,
/Johannes, Excito
