Thanks for having taken a look at this patch series. Jens asked for data
that shows that this patch series improves performance. Is this
something Samsung can help with?
We analyzed the NAND block erase counter with and without stream separation
through a long-term workload in F2FS.
The analysis showed that the erase counter is reduced by approximately 40%
with stream seperation.
Long-term workload is a scenario where erase and write are repeated by
stream after performing precondition fill for each temperature of F2FS.
Hi Daejun,
Thank you for having shared this data. This is very helpful. Since I'm
not familiar with the erase counter: does the above data perhaps mean
that write amplification is reduced by 40% in the workload that has been
examined?
Thanks,
Bart.
