#263 closed Bug report

client: SFTP really slow

Reported by: anonymous Owned by:
Priority: low Component: Other

Operating system version:


-Version: FileZilla_2_1_4a binary from this site
-OS: Windows XP SP1

Filezilla shows really bad performance when accessing
my SFTP server. In my 100 MBit LAN is get 60kb/s
where pure FTP transfers at 6 MB/s. A friend of mine
had the same Problem accessing the same sftp server
with Filezille (same version) from the internet (speed
only 3 kb/s where it should be 80 kb/s). Using another
sftp client (SecureFX Demo Version) solved the Problem
so I think Filezilla is to be blamed.

I used this SFTP server for testing:
ProFTPD Version 1.2.2
Mandrake linux 8.2 kernel 2.4
openssh 3.4

FileZilla uses parts of PuTTY for SFTP connections. The
speed problem is caused by PuTTY, please read
tp-slow.html for details.
