I was speaking about a group setting like "group metadata-cache". Its just

Is there an example of a custom profile you can share for my ovirt use case

All,
We've found perf xlators io-cache and read-ahead not adding any performance
improvement. At best read-ahead is redundant due to kernel read-ahead and
at worst io-cache is degrading the performance for workloads that doesn't
involve re-read. Given that VFS already have both these
Not yet but we are discussing an interim release. It is going to take a
