Slow upload ftp in plesk 11.5

[Webroy]

I have have Centos 6 with plesk 11.5 (updated today to the latest version).

When i connect through ftp ( filezilla, proftp , cyberduck) the upload takes to lang , lots of time outs and a lot of failed transfers.

In ps -aux i see a lot of:

SLs 11:12 0:00 proftpd: banner - source ip: STOR

in the logs i see:

Jan 8 11:23:48 server proftpd[10045]: - FTP session opened.
Jan 8 11:23:48 server proftpd[10045]: - Preparing to chroot to directory '/home/httpd/vhosts/domainname.com'
Jan 8 11:23:58 server xinetd[6363]: START: ftp pid=10061 from=::
Jan 8 11:23:58 server proftpd[10061]: - FTP session opened.
Jan 8 11:23:58 server proftpd[10061]: - Preparing to chroot to directory '/home/httpd/vhosts/domainname.com'

So it looks like he keeps on reconnecting.

Reverse dns is checked and oke.

In the /etc/proftp.conf is":

IdentLookups off
UseReverseDNS off

Any ideas why ftp is so slow?

I'm having this same problem. It seems to be worse when I FPT to the server as a vhost user rather than root. If I login as root, it seems much quicker. Have you noticed this as well?

The problem i have may be related to windows 8.1 connecting to ftp, when i use a windows 7 pc all works fine so i have to find out why 8.1 is slow..
