Hi @Xazax-hun, is the PR still WIP?
Can you remove the [WIP] tag from the title if it is good to review?
Thanks, Fabian

> The current implementation of the serializers can be a
> performance bottleneck in some scenarios. These performance problems were
> also reported on the mailing list recently [1].
> E.g. the PojoSerializer uses reflection for accessing the fields, which is
> slow [2].
> For the complete proposal see [3].
