You should raise this with your hosting provider (you don't say if it's OnDemand).
We're a community of end users, we don't have anything to do with running your Confluence, and although we can provide general help, we can't provide support.
If it is a problem with your hosting provider, then one option is to move to another provider or host it yourself. If, for example, it's latency due to geographical distance, then you might select a closer provider. But you need to contact support and work with them to find out what the problem actually is before you think about moving.
