yes. it is linearly dependent on the number of cache files
you specified for the cache.

it depends on the number of cache files. if you don't
explicitly specify afsd's -files option, this defaults
to the number of blocks in the cache divided by 10. you
can discover your defaults with afsd's -verbose option --
it will display the cache parameters on the console at
system start-up time.

this is probably because it takes longer and longer
to add an entry to the /usr/vice/cache directory as more
files are added, but this is pure speculation on my part.
if you have an 80000 block cache (the default size), afsd
will create 8000 files in the cache by default. i find this
is way too many for single user workstations (500-1000 is
probably a better number), so i specify afsd -files 1000 .
HTH...
