No, I finally found the "culprit". Another programmer read a page on
the Firebird site stating how by setting that value to 1 increased
performance in some particular operation and he "ninja" applied the
change everywhere. For some reason, the 2.0 engine would still work
well (maybe it performs a "sanity check" ignoring nonsensical low
values below a thresold?) but the 2.1.1 engine would show the
drastical effects at full.
