@Taek well I'm glad it's not 4GB! I haven't uploaded any files. Only hosting. When the disk is idle (5-10% usage) Sia still uses about 25% of CPU. Not sure if this has any relevance, but there's about 233 GB of storage that's been used. I've also been running Storj to see how it compares and it does seem to be less CPU/RAM hungry than Sia. Although it's only using about 170GB of storage. So this might explain why. I can live with this issue for the time being, but not indefinitely! Let me know if there's any other info I can provide that will help. Good luck with the improvements!
