+====== Squid Package Tuning ======
+From: https://forum.pfsense.org/index.php?topic=57230.0
+<code>
+So that would be my suggestion:
+    Hard disk cache size 15GB
+    Hard disk cache system aufs or ufs (increase vfs.read like you did already) Test which
+    performs better
+    Memory cache size 32MB
+    Minimum object size 16KB (I set it to 64 KB because I do not want that so many small
+    files will be cached. This increases HDD read/write and my WAN bandwidth allows that
+     to download such small files directly from the web and not from squid)
+    Maximum object size 1GB ( ServicePacks do have sizeses until 1GB. If you do not want
+    to cache all kind of service packs than probably a size of 256MB will be enough to get
+    most of the available updates in cache)
+    Maximum object size in RAM 2MB (In RAM I would like to have only small files which could
+    be served very fast. I do not want to have a 100MB file in RAM which wastes much space
+    and could be served fast enough even from HDD)
+    Memory replacement policy LRU (RAM should cache actual objects)
+    Cache replacement policy Heap LFUDA (what to cache servicepacks and big files on HDD)

+====== How much memory do I need in my Squid server? ======
+From: http://wiki.squid-cache.org/SquidFaq/SquidMemory#How_much_memory_do_I_need_in_my_Squid_server.3F
+<code>
+As a rule of thumb on Squid uses approximately 10 MB of RAM per GB of the total of all cache_dirs
+(more on 64 bit servers such as Alpha), plus your cache_mem setting and about an additional 10-20MB.
+It is recommended to have at least twice this amount of physical RAM available on your Squid server.
