How long should it take for global direction and the possibility for speeding up

[asheroin]

According to the issuse from original repo(https://github.com/orpatashnik/StyleCLIP/issues/95), the author said that it should take aroud 4 hours within a local GTX1080 while others claim that 24 hours is need with even a better GPU.

I had also tried your codes for extracting global direction, and it took about 2 hours for first layer, which excepted to take one day or two for the whole processing.

So, what's the proper time costing for this proecss? Is it possible to speed up the process with better hardware, like multi GPU in single machine?
