about 20k ? (and not 2MB !)

How to tune the size of each "m.xxx" file in mdbox format , in order

more

mdbox_rotate_size setting sets the max size of one mdbox file.
There's
really no ratio setting.. It would be difficult since as more
messages
get added more files would have to be merged, which would generate
extra
disk I/O, and typically people care about disk I/O rather than the
inode
count.
If such parameter exists, what is the typical value ?
Default is 2 MB files.
