The swap index file is "compacted" every time you rotate the logs (squid

I have a patch which improves this by not swapping out objects to disk
it is is known that the object is too large to be cached. See

Reducing the cache_swap_high&low is the same as reducing the cache_dir
size.

I prefer to use cache_swap_log to move the swap index files out of the
cache partitions. This makes Squid handle a full cache_dir partition
gracefully.
