If you do not need the cache to survive Squid crashes, use memory cache. > cache_mem 1024 MB > > in my config.

This will help even if you later decide to use a cache_dir in addition to the memory cache (for some valid reason). I do not know of a simple way to answer that question (I always look at cache.log with high debug levels), but I hope others on this list do. If that way does not exist, we should add code to Squid to support such answers. Good luck, Alex.
