speed up addClusters

[limiao20]

Dear ArchR Development Team,
I am using the addClusters function with method = "Seurat" and resolution = 0.8. While clustering 9 samples takes approximately 9 hours, clustering 35 samples has already taken over 180 hours. Is this computation time reasonable? Are there any optimizations or alternative methods within ArchR to speed up this step?
Thank you for your assistance.
