I was just thinking about something with VFAT and how ppl have mentioned how doing a simple 'ls' is slow. I was browsing the 'fs/dcache.c' code and wondered if this might be why. [I realize FAT has its own cache, but I think it still uses dcache (?). I haven't looked at it closely enough to know. (Since this just popped in my head anyway)]
Code snippet from dcache.c:
/* * Don't bother caching long names.. They just take up space in the cache, and * for a name cache you just want to cache the "normal" names anyway which tend * to be short. */ #define DCACHE_NAME_LEN 15 #define DCACHE_SIZE 128
For the sake of experimentation, I'm going to increase the NAME_LEN on my machine and see if it makes a difference.
You know, those numbers above might be a handy /proc tunable entry. I might just do that too. :)
