when i am running multiple sync in parallel the data ingestion become really slow how to solve this issue

The issue of slow data ingestion when running multiple syncs in parallel could be due to a variety of factors. Here are a few suggestions based on the information provided in the knowledge sources: 1. Isolate each stream into a separate sync job: This could potentially improve performance by reducing the load on each individual sync job ([source](https://discuss.airbyte.io/t/2416)). 2. Allocate more memory to the connection: This could help if the issue is related to resource constraints. You can do this by following the instructions in the [Airbyte documentation](https://docs.airbyte.io/operator-guides/configuring-connector-resources/#configuring-connection-specific-requirements) ([source](https://discuss.airbyte.io/t/2416)). 3. Upgrade your connector: If you're using an older version of a connector, upgrading to a newer version might help. However, keep in mind that some upgrades might trade speed for stability ([source](https://discuss.airbyte.io/t/2416)). 4. Check your logs: If the issue persists, it would be helpful to check your sync logs to identify any potential bottlenecks. You can also share these logs with the Airbyte team for further assistance ([source](https://discuss.airbyte.io/t/2416)). Remember, these are just suggestions and the actual solution might vary depending on your specific setup and the nature of the issue. If you're still experiencing problems, I would recommend reaching out to the Airbyte community or support for more personalized assistance.
