Are you writing scanlines or tiles?
Scanlines. Seems to be in the ZIP compression. When I turn off
compression it runs nearly as fast as 1.4. I haven't fiddled with the
other compression options.
I'm not sure if enabling threads will make a difference. I'm pretty much
using the default constructors for everything.
Thinking I may have built the library with the wrong optimization
settings, I went back and kicked everything up a notch, but it's still
quite a bit slower. Checked on both Linux and Windows.
Thanks for checking, Piotr.
Ok I nailed it down. My new exporter is converting the alpha to 4
channels and saving all 4 channels. 4x slower, duh. Sorry for the false
alarm.
