How did you ascertain that DB communication is a significant portion of the time? That is not my experience with DBD::ODBC and MS SQL Server with two exceptions which are a) when retrieving very large result-sets (and this could be improved by using array binding in DBD::ODBC but I've never had the impetus to do it myself) and b) when using dynamic or server-side cursors.

I'd be most interested in your usage case if it really demonstrates a high proportion of the time in DB communication.

Unlike some other people who claim using ODBC slows everything down (their usual reason is based on ODBC adds another layer over the TDS protocol and hence it must be slower) I've seldom seen an actual real life case with numbers that categorically proves adding ODBC makes a signifcant difference.
