Listing of a directory with more than 20000 files via FTP takes a long time

  Is there any way to downgrade the ftpversion to a previous one? I have some servers with lots of users doing LIST comands with a few hundrs of files per user and the CPU is super high.

  Hello, 

  Yes, downgrade is possible. Older package for your OS could be found here:

  https://pkgs.org/download/proftpd

  There are several guides available on the web on how to downgrade package in rpm- or deb-based OSes. The only thing that should be done is to backing up configuration files: 

  /etc/xinetd.d/ftp_psa
  /etc/proftpd.conf
  /etc/proftpd.include

  However such procedure has not been tested in Plesk environment and that is why I could not recommend one or another way of package downgrading.

  Hi Konstantin,

  The current package installed in plesk says "This package is built for PLESK with our own mod_quota patch." I'm afraid that if I install a package directly from pckgs.org I might lose some functionality or that plesk will overwrite it in the next update. 

  Is there any way to find and install the older package from the Plesk source? Or do you think that is the same?

  Name        : psa-proftpd
  Version     : 1.3.6
  Release     : cos7.build1708180220.17

  This package is built for PLESK with our own mod_quota patch.

  Hello,

  I have double checked this question and can confirm that there is no possibility to downgrade psa-proftpd package as there are dependencies on plesk-web-hosting package. And we do not recommend you to do such downgrade because slow directory listing is caused by additional security checks which provide your server with better security.

  Great! I guess we will have to wait until the ProFTPd bug 4360 is resolved

  My two cents are that is not just the case with 20.000 files, a bunch of users with directory listings of 500 items can also bring the server almost down :(

  @Dani Mora

  I also hope that proftpd will fix that soon. 
  You can also split folders with large amount of files to several sub-folders until the fix become available.
