[Proftpd-user] transfer performance

[Brad K. <br...@kn...>]

Hello,



I am getting customer complaints about the transfer speeds.  I need some
help to try to diagnose what is going on. Proftp has a public ip address,
so there are no NATs and is firewalled on the host with ufw.  The host is a
nfs server with user home dir.  Proftpd allows pam users to access the
files in their home dir.  I am not sure how to diagnose this.  The internet
feed is a 1Gb/s.  I get an upload speed of 34.9 MiB/s. on a 620 M file.  I
realize there are a lot of factors that can play a role in this transfer.
For now I want to focus on proftpd and see if it is performing like it
should.  Thoughts on how to go about this?



TY

Brad
