Just for completeness, I thought I'd share my measurements for release
branches other than 3.3.x.
Currently, there is some controversy as to whether 3.4/TOT is actually
slower than 3.3. My measurements
consistently confirm this thesis, although some folks apparently found
the reverse to be true. A suggestion
has been made (on this list, I believe) that 3.4 may be slower on small
files but faster on big ones. So,
is my test case considered small or large? The structparser.cpp file
itself is indeed very small, but it
pulls in a lot of Qt and STL gunk via #include and balloons up to 1 Mb,
which I would no longer consider
small. So, if someone (other than me) could do some systematic
3.3-vs-3.4 measurements and post the results
here, that would be great.
