To all,
I've got a query performance problem I'm trying to track down. I was
hopeful that 5.6 with RFC 52 implemented might help me, but it seems to
have no impact.
Are the changes for RFC 52 implemented for OGR ODBC connections?
Thanks!

The improvements are limited to native drivers only, principally Oracle
Spatial and PostGIS.
Brent,

The strange thing is the image render is quick (a few seconds), but the
nquery+mapshape (rectangle) with the processing of the template is several
minutes. And while it opens/reads/closes the template file for each
record(!), I

Yup. What sort of an example would help?

Frank,
With the new changes, the query takes about 5 minutes (2.5 minutes for
the first pass and 2.5 minutes for the second) to return the 868
records.
Using the old mapogr.c it would take 2.5 minutes (the first pass) + 1
minute/record (the second pass) = 15 hours (est). This is connecting t
