Was it similar to 'sf update' ? please check it once.
sf update out similar but also uses progressive output, in read/write case it can't be done. The final throughput measurement is similar on both update and read/write.
True, that's what if we need a progressed throughput just use 'sf update' else normal 'sf read/write' It's look not good to me to add extra code on top of generic commands. What ever we wanted to extend features let's added it on 'sf update' than sf read/write, Sorry.
If I need to measure the time of commands, I use the "time" command ("time sf write ...") by enabling it via CONFIG_CMD_TIME. This provides all the needed information to detect performance changes.
But similar kind of implementations is present for fatload and tftp. So I thought having similar performance log for sf read/write will be good as well.
Yes, I understand. I also find this output helpful. But I'm not sure, if we should add this timing code to all these functions. Instead of just using this common time command, if needed. To keep the code size at a minimum.
Of course its no big code addition, so I don't really have any bigger reservations against it.
Why can't just use 'sf update' instead of adding again same code in 'sf read/write' since 'sf update' is doing more than just giving timing performance. Please try!
thanks!
