Performance issues after 6.4 update

We've had performance and worst, machines disconnecting from the share ever since the 6.4 upgrade.
So far these are the things we've had to do to get a temporary fix:
- Disable BitRot
- Switch off snapshots
- Remove the last week or so's snapshots
All of these issues seem to be down to the process 'btrfs-cleaner' kicking in every time a snapshot is being churned.
During this process (which runs at up to 100% cpu) the admin console is unresponsive and if a user is copying files to the share, they get kicked off the share.
By disabling snapshots, the NAS doesn't need to do this periodic cleanup of the metadata and users can work as normal.
The major downside is no snapshots, so no going back in time.
We have an escalated support case with a Level 3 tech, so hopefully an interim firmware release will be imminent.
I'm also starting to believe that the problem relies in the snapshot creation process. I've since disabled and deleted all snapshots for the time being and see if the performance improves. The shares that had the most issues were those with hourly snapshots, which is why I think our users we're being kicked ou so often.
Hoping for a quick fix soon.
