cd sal
edit cppunittester/cppunittester.cxx, define TIMETESTS
build
(should see the times for the sal cppunit tests on stdout because those
ones are not gbuild-ified)
deliver -link; cd sc; make -sr;
grep ms ../workdir/unxlngx6/CppunitTest/sc_filters_test.test.log
FiltersTest::testRangeName: 525ms
FiltersTest::testContent: 1146ms
FiltersTest::testFunctions: 411ms
FiltersTest::testDatabaseRanges: 424ms
FiltersTest::testFormats: 1039ms
FiltersTest::testBugFixesODS: 408ms
FiltersTest::testBugFixesXLS: 61ms
FiltersTest::testBugFixesXLSX: 350ms

for my claim about the times per format I edited
FiltersTest::testFormats and changed the loop three times to just get
three times for for FiltersTest::testFormats as if it did just one
format. Those tally fairly close to the individual format
FiltersTest::testBugFixesXX times shown above

the times are spat out to stdout, though in the gbuildified modules
output is only shown if a test fails, at the gbuild layer.

If someone has the time, sticking basically empty .ods/.xlsx file in
there would be also worth following up. i.e. how long does loading an
empty one take :-)

It all might be a bit easier to hack some of the performance things at
the stripped-down unittest loading level. And my times are with
--enable-dbgutil, so may be totally irrelevant for real-world .ods/xlsx
loading, even if obviously relevant for dbgutil using hacking.
