MongoDB page size fine tuning disabling the compression

We are having partitioned collections. Due to AWS disk limitations we have set the allocation_size to 64KB, internal_page_max to 64KB and leaf_page_max to 64KB The IOPS decreased dramatically however we noticed increase in storage ( 4X ). Collection r_09_2024 is with default parameters ( allocation_size - 4KB, internal_page_max - 4KB and leaf_page_max - 32KB ) Collection: r_09_2024 - Size: 1.23 TB, Storage Size: 412.03 GB Collection: r_10_2024 - Size: 1.43 TB, Storage Size: 1.71 TB Collection: r_11_2024 - Size: 1.13 TB, Storage Size: 1.18 TB What should we do to allow compression with bigger block size?
