tilebench helper
that can be used to benchmark LibreOfficeKit tiled rendering. It
builds by default on Linux, and should show up in instdir/program
If you run:
cd instdir/program ; ./tilebench `pwd` /path/to/test/doc.odt
then it should produce some nice output a bit like this:profile run: initialization - 263.4392(ms) load document - 1097.3644(ms) getparts - 0.0222(ms) get size of parts - 0.0784(ms) render whole document - 74.4882(ms) render sub-region at 1:1 - 175.5018(ms) render sub-regions at scale - 388.7520(ms) destroy document - 178.5827(ms) Total: 2.1782(s)Which gives some timings for rendering a dozen tiles of pieces of your document at different sizes. This of course exercises the
headless backend, which has quite some scope for
performance work. At least it's rather easy to use cachegrind to
profile the run-time there, and you find some
interesting
things.

In case it's not painfully obvious: the reflections reflected here are my own; mine, all mine ! and don't reflect the views of Collabora, SUSE, Novell, The Document Foundation, Spaghetti Hurlers (International), or anyone else. It's also important to realise that I'm not in on the Swedish Conspiracy. Occasionally people ask for formal photos for conferences or fun.
