Is this statement true about identitylQ's syslog event storage?

Yes, the statement istrue. Both logging and auditing in SailPoint IdentityIQ can have a negative influence on performance because they involve additional function calls within the application. These processes generate data that needs to be stored, which can impact performance if not managed properly. Extensive logging and auditing, particularly at high levels of detail, can lead to increased I/O and storage usage, potentially slowing down system operations.
