[Openexr-devel] Multipart Performance Question

[Thorsten Kaufmann]

Hey everyone,

 

Due to using a lot of channels we are quite often seeing slowdowns due to scanline interleaving. Now that we have parts i

Was wondering if parts come at a cost and how much of a cost.

 

Say I would put each layer (RGB) in its own part. How much would that impact performance in the case of using a single layer

At the end, the beginning or using half of the layers or all?

 

Basically the question is if a multipart image with each RGB as a part would perform as fast as a single part scanline image

When actually using all channels vs. using just a few.

 

Regards and a late congrats on 2.0 J,

Thorsten
