   Chrome allows up to 6 open connections per domain at a time. When there are more than 6 slices in dashboard, a lot of time fetch request is queued up and wait for next available socket. This PR is trying to allow [domain sharding](https://blog.stackpath.com/glossary/domain-sharding/) for Superset, and this feature will be enabled by configuration only (by default Superset doesn't allow cross-domain request).
