Speed v Version

I contemplating providing "encouragement" to a customer to upgrade from 
5.8.7 to something more modern. One of the overriding issues is "speed". 
The customer is fixated with "speed".

Unfortunately one of the major things the customer's clients do is 
"replicate" their ISAM data into databases, usually MS-SQL via DBI and 
DBD::ODBC. The ISAM data is always on Linux (and a few Unix) boxes. The 
replication is a batch process that must complete overnight. Currently 
it is a fairly close run thing.

I don't suppose anyone has done any speed benchmarking on the various 
perls to date? Still less on newer DBIs etc? All the customer's modules 
are circa 2005.
