Description of problem:
I don't know what is wrong.
Before I reinstall fedora 3, I get 9000KB/s with CPU less than 20%
usage with vsftpd, 

After I reinstalled, with same setting, 
I get 500KB/s with CPU100% when uploading files from LAN Cilent.
I tried vsftpd, proftpd but same result,

I didnt change anything just reinstall and update.

Any one has same problem or is this happens only me?

Comment 3 Thomas Woerner 2004-12-02 05:32:27 EST
You are uploading files to the linux host?
Then this bug should be filed against the ftp server.

Comment #2:
OK but you don't say WHAT process top claims is using all the CPU. Is it the FTP
server? Or is all CPU disappearing inside system I/O? Could you attach the
around the first 20 lines of top to this bug?
Comment 5 Petr Raszyk 2005-08-15 11:12:29 EDT
This is not a bug in Linux-ftp-client.Your ftp client is a MS Windows executable.
We could not reproduce your issue using Linux-ftp-client <---> Linux-ftp-server.
We did not receive 'the first 20 lines of top' to continue with your issue as
a Linux-ftp-server-bug.
