# diagnose debug application authd -1 ----> checking timeouts and possible errors
1) Disable NTLM (if used with FSSO) for testing.
NTLM is heavy and can create peaks of memory, especially with lots of users and/or with polling mode on Collector Agent ).
High CPU usage for authd can be caused by the high number of problematic authentication requests (i.e.: NTLM credentials are not provided or NTLM requests are started as system processes) flooding the system with repeating attempts to send logon.
2) Try to optimize the Collector Agent.
- Make sure that the cache is enabled. - Raise the Worker Thread to 512 (Advanced settings > Worker thread count). - Switch to DCAgent if polling mode is used.
3) Check eventual conflict between server Windows server and FSSO Agent (64-bits versus 32).
