In some sense, yes ptolemy is performing much worse
than yevaud in that
ptolemy manages to render only something between 0 and 50 or so
metatiles per minute whereas yeavaud achieves about 3 - 6 metatiles per
second. However, the big question is is it doing something comparable?
I.e. is it a problem that the OS / DB isn't tuned optimally, or is it
simply doing something much harder?
Looking at the Tirex-statistics for ptolemy the following question
comes to my mind:
Does Tirex really render meta-tiles?
It rather looks like every tile (256x256) is rendered on it's own.
According to Frederik, Yevaud renders a meta-tile of 8x8 'normal'
tiles per request. If so, that could explain a lot of the different
