Limiting the number of simultaneous upload

#1 Post by Kalissar » 2014-04-20 03:10

Hello everyone,

I've set up a FTP server for my LAN, and I've made some observations.

When I upload a single file on the server, I get a certain throughput, usually 12Mb/sec
When I upload two files simultaneously, I get a certain throughput per file, usually 3Mb/sec
I've done a little math in my life, and I think 2x 3Mb/sec isn't as much as 12Mb/sec.
Let's say I have also done a bit of computer science in my life and admit that the time required to sync the different copy threads in both client and servers are responsible for the diminushed total throughput (actually it's just a guess, I might be totally wrong).

Third and last observation, when I try to upload more than 2 files, it justs queues the different files and upload 2 at a time.

So here is my question : in order to always get the maximum uploading throughput, can I limit the number of simultaneous upload to 1 ? But still queuing the remaining file to transfer, that is.

Thank you for your responses.
Regards,

You can configure the amount of simultaneous transfers in the settings dialog of FileZilla.

Believe me, I searched before posting this :/
Then I found the throughput limitation and thought it was only possible this way.
Anyway, thank you very much, finally found the option.

Now is there a way to apply this limitation server-side ? Because in the server setting dialog I only find "Speed limits" settings.

Thank you again

You can limit the amount of connections the server accepts, but that has side-effects, e.g. after connection failures.

In FileZilla Server, only through the max. number of users (global), or 'Maximum connection count' and 'Connection limit per IP' (FTP user account or group). Generally, a server has no way to limit transfers, that's solely a client setting.

Hi, I was trying to find how to set up the number of simultaneous upload but I could not... I am sure there is a setup because I used FileZilla for years and it had uploaded 10 files at a time. But now, after reinstalling it, it uploads only two files simultaneously. Thanks in advance!

It's in the settings dialog.

Yes, it's in settings, under 'Transfers' tab. Thanks.

Upload is somewhere limited to only two connections per user or IP. I have the latest version and there is no Transfer tab.

There are two FileZilla products - Client and Server. You are confusing the two. Transfers tab exists only in the client. This thread is a mess.

FileZilla Server does not have any default connection limits. Thus, if you have nothing configured in this regard, then it's not FileZilla Server limiting you. Check also the account setting, there it is also possible to limit connections.


Btw, your number of threads seems to be completely blown out of proportion. How many physical (not logical) cores/CPUs does the machine have? More is not always better, due to the overhead.
