| Limit                                                 | Previous               | New                                             |
| ----------------------------------------------------- | ---------------------- | ----------------------------------------------- |
| Concurrent instances (running in parallel)            | 10,000                 | 50,000                                          |
| Instance creation rate (per account)                  | 100/second per account | 300/second per account, 100/second per workflow |
| Queued instances per Workflow [1](#user-content-fn-1) | 1 million              | 2 million                                       |
