But btrfs in practice was just simply unsuitable; not only were there basic reliability issues (corrupted filesystems) and really bad corner case behavior (full filesystem in particular), we noted that it was not actually fully endian neutral, at least at the time, which caused filesystems between x86 and a BE ISA to ...

btrfs is always going to be slow in write heavy workloads due to being a COW filesystem. If you need the extra speed in that specific workload why not just disable the COW features using chattrib.
