[GENERAL] DB access speeds, App(linux)<->PG(linux) vs App(linux) <->MSSql(Windows)

[Gauthier, Dave]

Hi:  I'm trying to get a 10,000 ft understanding of the difference in DB access 
speeds for two different scenarios...

Scenario 1:     Apps are on linux.  PG DB is on linux (different server than 
apps)
Scenario 2:     Apps are on linux.  MSSql DB is on Windows (obviously a 
different server)

The apps are typically perl scripts using Perl DBI.
I'm thinking that since perl has a DBD driver for PG, that would be faster than 
going through ODBC to get to the MsSQL DB, but I'm not sure about that.

Any insights/guesses ?

Thanks in Advance.
