Hi Amos,
For my curiosity, I again checked same traffic with 3.1.19 and it is
working fantastic.
I really feel that, in 3.1.19 squid caching performance is superb while
considering 3.2.3.
I would request that once you verify caching mechanism of 3.2.3 with
3.1.19. I mean some changes are there at code level or something.
