Is mdconfig in FreeBSD and zRAM in linux are same?

[Prateek Dilip Halwe]

Hi FreeBSD Hackers,

Hope you all are doing good.

*Introduction:*
I was looking to experiment with my machine by improving its performance by
fastening or minimizing the page swapping from the disk.

I came across something called as zRAM <https://en.wikipedia.org/wiki/Zram>
in Linux, I searched the same for FreeBSD, I came across mdconfig. For more
details on zRAM a good link is here
<https://www.kernel.org/doc/Documentation/blockdev/zram.txt>.

*Question:*
My question is, are zRAM and mdconfig doing the same job? Has anyone done
some experiments with zRam on FreeBSD, in my case Is it meaningful to
consider zram for FreeBSD, given that something like mdconfig is already
available in FreeBSD? If so, please share some details and result.

Thanks in advance!

Thanks & Regards,
