If the structure for the data sources is the same, it's better to combine them into a single source. This will also be beneficial if you need to compare the data across multiple sources in a single worksheet. If the same were in multiple sources, then comparing the data may need blending which can cause performance issues.
Embedded extracts should perform better in comparison to published extracts. Remember, there may be network latency issues when connecting to published extracts.
Best idea is to combine in single source and connect it.
Don't connect more data source in tableau, it will load very slow.
