Yes, I am aware of these changes, and I was the one mentioned by
Martin in his blog post complaining about poor DBD::ODBC performance.

Martin Evans made some changes based on findings I reported but OTRS
on Microsoft SQL Server using DBD::ODBC is still *much* slower than on
MySQL, PostgreSQL or Oracle, unfortunately.
