Decoding really slow?

device (laptop):
Ryzen 9 5950hx
RTX 3060

hash WtH3Bgx]WXxZWYkCu6f*ofWBR*j?IonhogNHRjj[ivxYRkR-oJbI
1280 x 528
decode: 320 ms 😱

hash WPRysgayxuj[xuoft7ayRjj[WBay~qj[M{ayofayM{fQxuayt7of
600 x 600
decode 150 ms

Is it really normal?

No! Decoding should be much faster. Can you provide the images you used to benchmark?

I'll take a look on it.

Attached is one of it. I don't know what the other one was, but I can reproduce the slowing decoding with any image on any device :-(

This is the graph of the time to decode vs components X/Y option.

I will check if I can improve the performance...

I've testet several implementations of decoding (incl. Wasm), but it looks like there is a bottleneck at the pow function, which is called exponential relative to component x/y setting and the resulting image dimensions.
As far as I can evaluate, it cannot be further improved (even though Bytecode is little better), but its all about the decoding processors clock rate :/

I will take a look into implementing the Wasm solution though.
