Speed of Cell-Cell interaction analysis on scRNA-seq data

Question

[miyeok]

Hi all,

i am trying to perform Cell-Cell interaction analysis on scRNA-seq data processed by Seurat. And I'm using Cellchat for analysis package, but it is taking forever, I have about 10k cells in each samples. and total sample numbers are 8. By the way, my computer have 12 CPU core num. If there is a more faster way or package of cell-cell interaction analysis (LR-interaction)?

Any anwsers would be appreciated.
