When running a sync via the SyncEngine, slow performance is experienced and an error is visible in the HostServer log file.
The following error is visible in the HostServer log file: "Transaction (Process ID 54) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction".
When identities are synced and the provider (K2SQL, AAD, AD) returns users, groups or properties that was already synced, it was picked up as a change to the identity and in turn generated more and larger sql commands.
