find out the transfer rate

[bahar ertik <ba...@gmail.com>]

Hi,

I am trying to transfer files from my server to a client using ftp in java
and this works without any problems.
My question is: Is there any way to find out the transfer rate, MB/s, of the
transfer?

Best Regards

If you are doing what Miroslav said, I'd rather believe that it is your
'manual calculation' which is wrong. This should be with files of some size,
otherwise the difference might be related to different starting points
(e.g., with some firewalls that open/close ports automatically -but slowly-,
 passive mode can have quite different results for small files).

Why don't you check your transfer rate against the one that lftp or
filezilla report?

Dividing bits over seconds is quite simple, each xfer is not going to be
exactly the same even if you send /get the same file from/to the same
server. For whatever reason your xfer rates seem reasonable, so they are
probably correct.

I have tried that but this doesn't give the correct transfer rate. Because
the result I get is far away from the result I get when I do it manuallt,
stepwise!
Manually done the transfer rate for the put is 17.09 MB/sec and get 87.83
MB/sec.
Recording the time at start and end gives the result  put 11.11 MB/sec and
get 33 MB/sec.

Record the time at the start and end of the operation and divide tht with
the file size.
