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. :)
