I don't think this is a "bug" in Nuke's EXR reader code... I think it's a
limitation of OpenEXR's design. Since files are scanline-interleaved, all of
the channels in any scanline must be decompressed and read in order to
extract the RGBA data (or any other arbitrary channel).

Hi!
We noticed EXR read performance drops if there are a lot of layers
included in the EXR, even if only standard RGBA channels are requested.
According to TheFoundry this is a bug in the EXR reader plugin which
causes all channels to be loaded. Does anyone have a starting point
where this problem lies in the source code given?
Thanks a lot,
Phong
