in thread Much slower DBI on RHEL6

They are different versions of DBI, DBD-MySQL, Perl, and MySQL but on each machine they are the versions that come with RHEL. I did not customize any of the packages, got them directly from RH.

    Well, then. On each machine, install the version of everything (or one thing at a time) mentioned above that exists on the other machine, and see if the programm gets faster or slower. Yes, it involves work.

      Well, that would be great but I don't think I would be able to install the RPMs from RHEL6 on a RHEL4 and vice versa without a huge amount of RPM dependency issues... expecially with Perl.

        "...a huge amount of RPM dependency issues."

        AKA Dependency hell or RPM hell in this case :-(

    Getting well off-topic now, but do bear in mind that newer versions of MySQL use InnoDB as the default storage engine, whereas older versions use MyISAM. Make sure that your tables on the different servers are using the same storage engine as that could account for big differences in times of operations.

    "They are different versions of DBI, DBD-MySQL, Perl, and MySQL..."

    It would be nice to hear more about this issue. Please report.
