Enhanced output performance of LRCC and CLASSIC shifters

My computer configuration is as follows: AMD Ryzen 9 8940HX with Radeon Graphics (2.40 GHz), RAM: 48.0 GB, NVIDIA GeForce RTX 5070 Ti Laptop GPU (12 GB), SSD: 3TB. I use Lightroom CC for image editing and apply a color mask. The processing speed is normal, but outputting 5-10 JPG files at a time is extremely slow (my photos are RAW to JPG, and the RAW files are 42 megapixels). The software performance is already set to high efficiency and GPU, and the network is 5G. Please improve the output efficiency.
