Is there any mysql optimisation I can do to improve this or is it another
threading issue where the scheduling is done by the recording thread or
something equally daft.
I regularly run optimise_mythdb and the db appears to have updated

The db is on a raid1 array that shares a disk with the raid5 array that
stores the recordings (i.e. one partition of the drives is part of the
raid1, another partition a part of the raid5). Is there anything that
