Help With Gaining Maximum Read Speed

[jakanaka]

I have a zfs pool on /mnt/tank and md raid on /mnt/spool. I have my media content there. The issue i face is the mergerfs mount point gets very slow on high io operations with default settings. I read the readme and tuned the options like this now

mergerfs /mnt/tank=RO:/mnt/spool=RO /mnt/media -o security_capability=false,xattr=noattr,nonempty,allow_other,use_ino,cache.files=off,cache.readdir=true,cache.symlinks=true,symlinkify=true,symlinkify_timeout=0,fsname=media,threads=8

this seem to have got this to at least a usable state bt the original fs is more faster. i don't write at at the the mountpoint. they are all video and static content. any help on how to achieve maximum read speed and io operations

If you are using symlinkify then you aren't even using mergerfs for reads.

There is really nothing additional to say besides what I have in the docs. Unless you provide more information there really isn't much to say. I have sections on support and benchmarking which gives you a bunch of details to share.

symlinkify_timeout=0 means everything will be symlinked directly, right? can you suggest any other flags i should add or change?

[trapexit]

It means as it mentions. That once the current time - mtime exceeds that value it will be symlinked. And the file must be read only.

As I said... I've nothing to add without more info / context. If I had anything additional generally to suggest it would already be in the docs.
