The performance problem when OS of Webserver is WindowsServer2012R2

Hi!

We have two JDE EnterpriseOne 9.1 instance on TOOLS9.1 and 9.2 with two AS400 Enterprise/DB LPARS on V7R1.

<Cause>
After E1 Webclient login execution of SQL via a webserver(WindowsServer2012 R2) is slow.

<Oracle SR GCS comment>
The difference in the Tools versions (9.1.5.5 > 9.2.0.6), it's being talked about as a performance on the database driver side
such as problems of a performance in a JDBC connection of DB2 in Windows Server 2012 because the difference in the operating systems
by which a web server works (Windows 2008 / Windows 2012) seems caused, and query processing of a data base is related.

<Question>
The version of the jt400.jar is being changed and inspected variously, but the situation doesn't change.
Can there be someone who was the same phenomenon?

<Inspection>
