Is Squid 2.6 too going to eat up to maximum_object_size of memory while retrieving a new object, before it decides whether to write it to disk? I'm considering to increase this value, so it never hurts to ask. Thank you. From http://man.chinaunix.net/newsoft/squid/Squid_FAQ/FAQ.html#toc8.1
Squid-1.1 also uses a lot of memory to store in-transit objects. This version stores incoming objects only in memory, until the transfer is complete. At that point it decides whether or not to store the object on disk. This means that when users download large files, your memory usage will increase significantly.
