    Hello.

    # Container start command
    $ sudo docker run -h db2-12_1 --name db2-12_1 --restart=always --detach --privileged=true \

    $ db2level

    DB21085I  This instance or install (instance name, where applicable:
    "db2inst1") uses "64" bits and DB2 code release "SQL12012" with level
    identifier "02030110".
    Informational tokens are "DB2 v12.1.2.0", "s2505201240", "DYN2505201240AMD64",
    and Fix Pack "0".
    Product is installed at "/opt/ibm/db2/V12.1".

    $ time db2 create db test
    DB20000I  The CREATE DATABASE command completed successfully.

    real    74m58.681s
    user    0m0.036s
    sys     0m0.052s

    75 min (!!!) for a simple `CREATE DATABASE` command. 15 min worse, than with 12.1.1.

    Does anybody see the same behavior of containerized DB2 in docker?
