[ovirt-users] slow kerberos authentication

I'm using kerberos authentication in ovirt for the URL /sso/oauth/token-http-auth, but kerberos is done in Apache using auth_gssapi_module and it's quite slow, about 6s for a request. I'm trying to understand if it's apache or ovirt-engine that are slow. Is there a way to get response time metered for http requests inside ovirt instead of seen from apache ?
