Just my tuppence really but its not a stupidly low value in freetds.conf
is it!?

There is a default block size:

[global]
# TDS protocol version
tds version = 8.0
initial block size = 1024

I know nothing about dblib or perl but I do know I have had a similar
problem in the past where the block size was to small for what was being
retrieved.

Regards

Jim Vanns
