 * `Fixed`: auto syncing performance up to 30x times compared to [v1.0.2](https://github.com/exAspArk/batch-loader/blob/master/CHANGELOG.md#v102--2017-09-14). Ruby `Forwardable` with `def_delegators` is too slow.
 * `Fixed`: GraphQL performance up to 3x times by disabling auto syncing in favor of syncing with [graphql-ruby](https://github.com/rmosolgo/graphql-ruby) `lazy_resolve`.
