Android Question FTP Slow Upload

[mohsen nasrabady]

hi i try to upload file with net library to my ftp

the upload speed is good with samsung s5 and huawei that i tested

but on my Sony Arc s the speed is very bad low 1KB/S

i searched and seems the way to solved that is SetBufferSize to a number like (1024*1024)

how can setbuffersize ftp of net library?

 

[DonManfred]

you want to set the buffersize to 1MB? Usually is has an size of 512byte, 1k, 2k, 4k, 8k, 16k, 32k, 64k... But not 1024k

hi thank you for answer

do not important the size of buffer i just want to solve my problem

i many search about common apache i think the default buffer size is 0

 

[DonManfred]

common apache i think the default buffer size is 0

What has apache in common with ftp-transferrates? It is most probably not apache who answers ftp-requests on serverside.
Maybe you need to check your ftp-server-settings

So it's not a matter of the server (ftp or apache).

But I do not have the answer (because I'm still sleeping, huh! )

The streams are buffered. It is not related to the buffer.

Are you testing it on a local network?

the ftp upload speed is good with android 2.3 , 4.4.2
i just have problem with my sonyericson arc s (custom rom 4.4.4)
i have problem too in this device with ESFileExplorer and other ftp app

Then it seems that you need to contact the author of this Custom ROM to fix this issue.

i consider again
when the phone connects to modem speed is ok
but when connects to a repeater speed is very bad slow
is there solution?

but in the official rom there is no problem

 

[Erel]

It sounds like a low level problem on the device itself.

i have the same problem

sometimes the uploading process takes 4-5 sec (a 10kb txt file) sometimes 1 minute

what could be the reason for that??

 

[Erel]

The FTP object opens a standard socket and connects to the server. There could be many network problems along the way. However by itself the FTP object will not make the communication slower or faster.

 

[KMatle]

Firewall? (active/passive FTP)? Can you connect to the router directly (instead of the repeater) or to another server (local?) to check it?

 

[mohsen nasrabady]

when connect to a modem direct the speed is good but with repeater very slow
my phone have no antivirus are firewall and i tested in active and passive mode
