Login performance of BI Launch Pad

Hi,

The environment of BI4.1_SP4.

Please inform me about a logon performance of BI Launch Pad.

The first time logon on a day and first time report indication.
It takes time very much.

After a user name and a password are input from a logon screen of a BI launch pad.
It takes time remarkably until a home screen is indicated.

The first time user: First time = 40 seconds, 2nd time = 2 seconds

[Report View]

The first time user: First time = 23 seconds, 2nd time = 3 seconds

Would there be any countermeasures?

Regards,

Michiko
