Would it be worthwhile installing squid on a pfsense box if the connection is fibre, ~10ms ping Wellington to Auckland, ~950 Mbps down, ~450 Mbps up?

There are 4 people in the apartment only. The box is a AMD A6-6400K APU with Radeon(tm) HD Graphics, 32GB DDR3 RAM, Intel-82571EB-Gigabit-Ethernet-Controller https://ark.intel.com/products/20720/Intel-82571EB-Gigabit-Ethernet-Controller. I'd put the cache in a ramdisk, say about 26GB and limit the cache size to 25GB.

I'd enable it as a transparent proxy, and don't want to specify it as an explicit proxy, nor have to deal with people telling me website x isn't working anymore.

Since the box is working well atm, I don't want to enable something without first asking around. I read some of the pfsense forums and reddit and it seems like squid isn't going to be of much use?
