[Nfd-dev] How to see data retrieve / download time using "ndngetfile" command?

[Klaus Schneider]

We are currently updating the ndncatchunks code: 
https://gerrit.named-data.net/#/c/3432/

you can check the code out via "git fetch 
https://gerrit.named-data.net/ndn-tools refs/changes/32/3432/4 && git 
checkout FETCH_HEAD"

It contains a function printSummary() which might be what you want:

> void

> {
>   time::steady_clock::duration dur = time::steady_clock::now() - m_startTime;
>   double timePassed = static_cast<double>(dur.count()) / 1000000; // in ms
>   double throughput = (8 * m_receivedSize * 1000) / timePassed;
>   std::string throughputUnit;

>             << "Time used: " << timePassed << " ms" << "\n"
>             << "Goodput: " << throughput << " " << throughputUnit << "\n";
> }
