Filemanager/FTP Upload is very slow

[Vs Nu]

Hello
Most of the users are complaining that cPanel filemanager and FTP Uploads are very slow even i had contacted the Cloudlinux dept if Cagefs or other limits causing the issue but they said there is no issue from cloudlinux end


Please help me on how to fix this case

IO is normal
server load is normal

No hardware issue (Confirmed by doing hardware investigation OVH)

and do you experience the same? Is it interrupting as well? (the upload) do you use any firewall? If you do have you whitelisted the passive range of the FTP server?

If you temporary disable the firewall does the fix the issue?

I hope no because i had Reinstall CSF and it was running with CSF Default values !!

any other things to check in cPanel ??

Well can you try? Just run csf -x to disable it then csf -e to enable it again. Your settings won't be lost.

I had tried disable the CSF and uploaded it but still same issue (I had enabled firewall again)

I'm not sure what could cause this without having access to the server. Have you asked your hosting provider yet? Maybe @cPanelLauren has some further ideas here.

@cPanelLauren has abandoned us! Well, just for today though :D

FTP slowness likely isn't something that would be related to the cPanel tools on the server. If you have access to one of the networks where users are reporting the slowness you could try a direct FTP connection over the command line to see if the speed changes there, which would at least rule out the client, but there aren't any cPanel settings or options that would limit FTP speed. It might be a good thing to speak with the hosting provider about to see if they can run additional tests on the network itself.
