Reconstruction time too high

Hello,

Despite a powerful machine — AMD EPYC 7402P 24-Core Processor // 192 GB RAM // Nvidia A6000 (47 GB) — the reconstruction of a 100×100 m mesh takes 3 hours, and a 400×400 m one takes more than 14 hours !

Can’t we optimize these computations?

Our current component have 12k photos for a large model (25 km²). So in this condition we have 12000 hours of calculation.

Thanks in advance for your help.
