7.85H Transfer rate/speed calculation issue.

Postby bduncan on Sun Jun 25, 2017 1:05 pm

This forum doe NOT say no bug reports, so I assume this is OK.

Something seems to be wrong with Linux transfer rate/speed calculation.

I ran a test profile a couple of times with the same similar results.

I was using the 64-Bit Intel With Web GUI trial.

Example:

Profile : test
Start time: 25-06-2017 12:36:32
Completed : 25-06-2017 12:45:51
Short Results: 1053 copied (54.9GB)
Detailed Results
-----------------------

Copied To Right Side: 1053 (54.9GB)
Folders Created On Right Side: 12

Average copying time per file : 1.5 s
Copying time for fastest file : 0.0 s
Copying time for slowest file : 123.1 s

Average transfer rate per file : 35299.8 kB/sec
Transfer rate for slowest file : 2.1 kB/sec
Transfer rate for fastest file : 69258.2 kB/sec
For the fastest/slowest rates, only files at least 1 kilobyte in size were counted.
------------------------

The above job took just over 9 minutes.

If the average was really 35,299.8 kB/sec, this job should have taken around 26 minutes to complete, not 9.

Monitoring network traffic for this job I saw it contantly at 105-110 Megabytes per second, the transfer rate for fastest file also seems off.

The average transfer rate is averaged "per file", which means that it's not the overall average transfer rate per GB. You cannot really do anything with this value. You cannot multiply it with anything.

The value for the fastest file is certainly not off, because Syncovery copied multiple files in parallel. The default is three.

These rates are just not what you are looking for. Their usefulness can certainly be argued about.

Did not realize it defaulted to 3 parallel copies by default per job.

You are correct, when I changed it to 1 for the job, the calculated rates reflected that:

Detailed Results
-----------------------

Average transfer rate per file : 97861.1 kB/sec
Transfer rate for slowest file : 169.4 kB/sec
Transfer rate for fastest file : 105847.3 kB/sec
For the fastest/slowest rates, only files at least 1 kilobyte in size were counted.

Couldn't the Detailed Results include a Average transfer rate variable that = Average Transfer rate per file * number of simultaneous copies, then it would show an overall throughput for the particular job regardless of how many simultaneous copies the user has set?
