I've recently come across redis being installed and configured on single server low traffic stores.
Generally the default response for anyone when reporting their Magento 2 store is slow (which is everyone) is for the web hosts to install and configure redis (among other things). However so far it is my personal opinion that having redis adds an additional barrier when trying to load new content and I see very little performance gain.
Knowing a bit about the technology and how it works it is my understanding is that with a webserver using ssd's with low traffic the benefit is minimal. I'm wondering if anyone in the community has some benchmarks on low traffic stores with a before and after to confirm my theory.
I do however understand how redis has a positive impact on high traffic stores.
I'm keen to hear other's experiences. I see questions on configuring redis but I don't seen that anyone has asked this question on magento 2.
