portal login - logoff slow :
I've got a big problem with my portal. Since one week it started to go slow while load the main login page and while login / logoff procedure.
I've checked that component "UME:SAPJ2EEAuthenticator:logon " has some problem (average gross time 91 seconds from JAVA SYSTEM REPORT, nwa).
I've checked db parameters (Oracle 10.0.2) but everything seems to work fine.
LDAP System (MS Active Directory) works fine.
Any ideas about that ??
