Why PureFTPD so slow when uploading multiple files ?

Hi All !

Thanks for helping us everyday !

I’ve just install an Ubuntu 18.04 server following the Perfect Server ( instructions.

We’re using PureFTPd Server for FTP connections.

I’m hosting the server on DigitalOcean Droplet, and when I run a speedtest I get:

root@cloud01:~# ./speedtest-cli Retrieving configuration… Testing from Digital Ocean (… Retrieving server list… Selecting best server based on ping… Hosted by Ridge Wireless (Cupertino, CA) [5.08 km]: 2.717 ms Testing download speed… … Download: 853.46 Mbit/s Testing upload speed… … . Upload: 683.06 Mbit/s

The problem is:

OLD Scenario - Shared Server in a Brazilian ISP When I send a 112MB file to the server (PureFTP too) it takes about 00:00:31 (average: 3.6MB/s)

NEW Scenario - VPS Droplet in DigitalOcean SFO2 When I send a 112MB file to the server (PureFTP) it takes about 00:00:34 (average 3.2MB/s)

Its not a big difference and it is ok for me.

BUT, When I send 100 files of 12KB:

OLD Scenario takes 00:00:06 (about 360KB/s)

NEW Scenario takes 00:01:45 (about 11KB/s)

The same happens when I’m deleting files, on the new server it takes too longer than in the old server.

So we know that the problem remains in working with a lots of file, and not with the size of the file. So, we don’t think it’s a bandwidht problem but in the communication between client and server before each file transfer.

Some people in other forums said it’s a DigitalOcen problem.

Any clue will be appreciate !

Thanks in advance !
