Filesystem hangs when navigating through directories

[roemer2201]

Dear All,

when navigating through the filesystem, explorer hangs and the taskmanager shows high read-activity on the disk.

My Setup: Win 10 LTSC 21H2 WinBTRFS 1.9 Seagate Exos 2X18 18 TB

This HDD contains two Read-/Write-Heads, each one can access one half of the available space, so I created two partitions on this disk (50/50) and setup BTRFS as Raid0 for data and Raid1 for metadata.

Please check the following video to get a sense of what is happening:

Can somebody explain this behavior and what can be done about it, so that navigating feels smooth?

Thank you in advance!
