I bet most of it is buffers and cache. Do you use zfs?

Yes

JayOK 2022-09-20 15:03:35
eng_mohammed_alnahdi 2022-09-20 14:46:25
Yes

Set vfs.zfs.arc_max to a minimum and see if it still consumes memory

too advanced. I google it and see several solution 😅

@JayOK can we skip this right now? because I want finished two books right now. I thought it will be easy solution. 😅

several of my systems have set vfs.zfs.arc_max set to 256 mb, and it works, for these slow storage systems

is it just add line in /boot/loader.conf
vfs.zfs.arc_max=”256MB”
?

rob2g2 2022-09-20 17:13:29
no, you have to write it in bytes
rob2g2 2022-09-20 17:13:39
256*1024*1024

rob2g2 2022-09-20 17:13:39
256*1024*1024

vfs.zfs.arc_max=”277872640″

eng_mohammed_alnahdi 2022-09-20 17:15:50
like this ?
rob2g2 2022-09-20 17:16:56

rob2g2 2022-09-20 17:17:08

Systems, Science and FreeBSD

What makes a platform suitable to both research and development? It is not simply the artifacts that are generated, but the tools that the platform brings to bear on evaluating the usefulness and quality of the research that is being undertaken. FreeBSD continues to push the boundaries of systems research through its adoption and extension of significant new technologies such as DTrace and LLVM. This talk looks at how the latest tools and techniques are being applied to systems research and how the tools enable us to find deeper insights and more clearly communicate and share our results with other researchers.

Dragos 2022-09-24 11:28:45
works if i put it under rc.conf?
Dragos 2022-09-24 11:28:57
