@kapa.ai any reason why the syncs are slower after upgrading from 0.63.5 to 1.1?

Based on the information provided in the knowledge sources, there are a few potential reasons why syncs might be slower after upgrading Airbyte from version 0.63.5 to 1.1: 1. Performance trade-offs: According to a response from the Airbyte engineering team, upgrades between major versions (like 0.x to 1.x) often include changes that trade speed for stability. As mentioned in the forum post, "an upgrade from

0.40.2

to

1.0.4

probably included many changes that traded speed for stability." [Forum Post: Airbyte ingestion slower after connector upgrade to 1.X](https://discuss.airbyte.io/t/2416) 2. Connector version changes: The upgrade may have also updated your source and destination connectors. Some connectors have had performance changes in newer versions. For example, the Typeform connector had a breaking change in version 1.1.0 that affected the state format of the

value helped resolve sync instability issues after an upgrade. [Github Issue: Significant sync instability after upgrading](https://github.com/airbytehq/airbyte/issues/33693) To address the slower syncs, you could try: 1. Allocating more memory to the connection, as suggested in one of the forum posts. 2. Isolating each stream into a separate sync job to help with performance. 3. Checking if any of your connectors have specific upgrade notes or known issues in newer versions. If the performance issues persist, it would be helpful to share sync logs and performance metrics with the Airbyte team for further investigation.
