I came across something called as zRAM in Linux, I searched the same for FreeBSD, I came across mdconfig. For more details on zRAM a good link is here . *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, Prateek Halwe
