it does not have a significant impact on performance, maybe I will have set something wrong but I doubt Disable dm-writeboost_disable Enable dm-writeboost_enable

Hi @pipes80-collab,

Can you describe what you did? I have completely no clue with these two figures.

pipes80-collab commented 3 years ago

I use the same command into the video

Sorry, I can't help you.

You need to share

Kernel version, writeboost version
What devices you use
state of lsblk
etc

to ask me for help.

But let's make a guess: Since the two figures show almost the same result, I bet you don't use writeboost at all. In addition, since the throughput is too high I guess you are trying to use solid drive as the backing storage, which isn't the usage of writeboost.
