Hi, Amos, thanks for your reply. I'll test the patch and use memory_cache_shared set to OFF. Sorry, I was wrong. Objects bigger than maximum_object_size_in_memory are not cached on disk. Although objects smaller than maximum_object_size_in_memory but bigger than 32KB were written to disk, I guess they got a HIT because Squid keeps a copy in memory of hot and in-transit objects. That explains why the UFS store was "ignored" when Squid was restarted. Thanks.
