You are forcing your system to swap by running it out of RAM.

Solution:

1) Reduce your cache size to about 15000 (possibly even less)
2) Reduce cache_mem to about 32 MB (or less)

Some other suggestions:

1) The L1 split of 16 in the cache_dir line is good for up to about 6500 MB
of cache. Since you are using more than that, adjust it accordingly.
2) Try using aufs or diskd instead of ufs for better disk performance. Aufs
performs better than diskd on Linux and is fully compatible with your
existing ufs cache store.
