I saw this in the release documentation for June 2008:
Compilation from sources
For convenience of both developers and users as well as to comply even more with open source standards, we now set/use the following defaults for the configure options
--enable-strict, --enable-assert, --enable-debug, --enable-optimize When compiling from CVS sources (as mainly done by developers): strict=yes assert=yes debug=yes optimize=no (*)
...
(*) IMPORTANT NOTE: Since --enable-optimize=yes is no longer the default for any case except binary packages, it is strongly recommended to (re)compile everything from scratch, explicitly configured with --enable-debug=no --enable-assert=no --enable-optimize=yes
Optimization here is to advice the C-compiler to optimize code. The MonetDB optimizer default pipeline can be seen with select optimizer; For further information see: http://monetdb.cwi.nl/SQL/Documentation/Optimizer-Control.html
This is why I assumed that I am compiling from CVS with the optimizer being disabled. So could you please clear that up for me? Is the optimizer enabled by default or not when building from CVS? Also, how can I tell if the optimizer is running or not when MonetDB is up and running?
Thanks.

After reading in the documentation that optimization is disabled by default, Where exactly does the documentation say so?
Unless you call nmake with DEBUG=1, we use -Ox, i.e., optimization is enabled by default...
Just check your nmake logs/output (without optimize=yes) to see which options are given to the compiler. (and potentially compare with that of optimize=yes to see whether there are any differences)
I added optimize=yes to my nmake commands. Nm, does nmake recognize/handle that option? I'm not aware that our Makefile do ...
I start MonetDB with MSQLserver.bat from the Install directory. Whatever I'm doing is working when I leave out optimize=yes from the build procedure. If I look at the original sql/NT/MSQLserver.bat and MonetDB5/NT/M5server.bat, I cannot see how they can result in mserver5.exe being called with --dbfarm=\dbfarm, as your -d10 output suggests ...
To add the output I have been asked for I added "-d 10" to Mserver.bat after "%MONETDB%\bin\mserver.exe" ... Mserver.bat is MonetDB4, not MonetDB5 . M5server.bat is MonetDB5.
MonetDB/SQL requires (and works with) MonetDB5, only, not (with) MonetDB4.
(MonetDB/XQuery requires (and works with) MonetDB4, only, not (with) MonetDB5.)
When running MSQLserver.bat like this, I don't get any welcome message at all. I immediately get the output I put here before. Your -d10 output says # config opt Monet_welcome = yes hence, I'd expect a welcome message ...

Thanks.
