Transfer Speed

[dogfood09]

Hi Guys ,

Ive run into my first issue , My single file transfer speeds are incredible slow, ave 3.8MiB/s , where as before they were at 27.8 MiB/s! , if i have concurrent downloads then im hitting my maximum bandwith at 28MiB/s but for some reason and i dont believe ive adjusted anything my single file transfers are so slow? Is there something i am missing?? or anything i can do?

Many thanks

Sorry if this is a noob question , i did scour the forums first

Could the server be congested?

Not too sure about that , i can download at full speed when ive selected multiple files , but a single file , no matter what file i try is extremley slow

Is it FTP over TLS or SFTP? Or only plain FTP?

[dogfood09]

Its FTP over TLS

Is the limit consistent for every additional file? So it is 2 x 3.8MiB/s for two files? If yes, it may be traffic shaping by the ISP, or a per-connection-limit on the server.

FTP over TLS is unknown traffic to the ISP. It might get confused by them with other types of encrypted traffic, like P2P, and thus limited.

Hi , yeah , if i selected 10 files to fransfer they all download at 3.8MiB/s , Ive heard it has something to do with the ISP , my single threaded download hits 49mb , where as my multi threaded download hits 220mb , will be call the ISP to see if anything can be done , as it never used to do that until i upgraded my line

My transfer speeds are really slow, arond 2.0MiB/s i don't know if there's a way to fix this

Depends. What speed should it be?

- Note that ISPs advertise in Mib/s (Megabits/sec). You need to divide by 8 to get the MiB/s (MegaBytes/s) speed.
- Upload speed is usually lower as download speed.
- Server or network congestion can greatly lower speeds. The slowest link in the chain determines the speed reached.
