For selects - to get all the information for the VDS we have multiple joins. Adding another one will hurt performance even more. For updates - we have vds_static thats hardly changed. vds_statistics that changes all the time. vds_dynamic is not changed allot - but is updated all the time because of the status. I think it's best to split it to the two existing tables (BTW - relevant for VM as well) but we don't update it unless the status has changed, which is a rare occurance? Actually - no. We can definitely see times we are updating vds_dynamic with no reason at all. I tried to create patches for that - but it happens from many different places in the code.
