Am trying to upload files with Filezilla to my server and the upload is somehow limited to 80KiB. The server can take up to 4MiB in upload and my connection has a 512KiB upload.

What should I check to see what the problem is.

Have you used more than 80KiB/S before? Were you trying to upload at peak times? –  Lewis Goddard Sep 29 '11 at 18:05
    
Are you using FTP, SFTP, FTPS or something else? Check your filezilla configuration for any throttle settings. –  Lekensteyn Sep 29 '11 at 19:45
    
When using scp o rsync I can go to the same server as fast as 440KiB. for the filezilla am using FTP and SSH. But if I use ssh from console via scp o rsync it goes faster than filezilla. –  Luis Alvarado Sep 29 '11 at 19:46
    
For the answer which should be question below the answer is for speedtest.net: 3876KiB Download / 480KiB Upload –  Luis Alvarado Sep 29 '11 at 19:48

There are a few things that could be limiting your speed:

  1. The receiving server: some servers limit up/download speeds depending on the protocol used (eg: I used to have a web hosting server that throttled HTTP downloads to 40 KB/s, but SCP worked full speed)

  2. Your ISP (ie: your upstream speed limit): if this is the case the only choice is to upgrade

  3. Your client (FileZilla): if you can upload with better speeds to the same server using the same protocol with a different client, it might be a setting on your client.

In my comment above I already explained that by using ssh or rsync I have a much better speed, so point 1 and 2 are not the problem. For point 3 I have not changed any of the default values for filezilla. Already checked for limiting options and none have something that says to limit my upload. –  Luis Alvarado Sep 30 '11 at 15:09
    
@LuisAlvarado Are you sure you are using the correct hostname and port for SFTP on Filezilla? –  NullUserException Sep 30 '11 at 15:14
    
yeap. 100% sure. Already checked that. just in case am using the 3.3.5.1 version of filezilla that comes with 11.04 –  Luis Alvarado Sep 30 '11 at 15:18

use speedtest.net to check your real upload and download speed.
usually the upload speed is half the download speed.

Edit: You may also check your speed limit settings for FileZilla which is located under Edit > Settings... > Transfers > Speed Limits.

This should be a comment. Already answered above in a comment. –  Luis Alvarado Sep 30 '11 at 15:15

Are you sure you are not confusing KiB with KB or something:

512KiB line is max: ((512*1000)/8)/1024=62.500KB max, don't know were you had your 80KB from but not from a 512KiB line I think.

Don confuse Kb with the IEC KiB. en.wikipedia.org/wiki/Kibibyte 512KiB is 512 KiloBytes, that means 512KB/Sec in terms of transfer. Your equation is for bits and not bits exactly but human readable ones when you multiply by 1000 instead of 1024. –  Luis Alvarado Sep 30 '11 at 15:14
    
Oh sorry, gl with your quest to find a solution for this. –  Bruno Pereira Sep 30 '11 at 18:58
