[SOLVED] Reason of Io read degradation

Ankita_kulkarni · 10-05-2021, 03:40 AM

Hi,
I am running iozone in auto mode on RISCV architecture. When I compare results two of different boards of same architecture, I see degradation in read operations only. What could be the reason for it? How can I proceed on the reason finding?

Thanks

No. Previously asked about IPCs and the architectures were different like arm & riscv. But now i am comparing for same architectures.

so without details the reason could be anything, for example line 25 in a config file.

Can you tell what details are required?

Thanks

1. exactly what hardware is it
2. exactly what is installed/running
3. exactly what did you measure and how, what was the result
4. is there any difference (hw, software, config, whatever) between these systems?

Just remember, you need to give all the details to be able to reproduce it by others.
