What caching configurations do you all use?
- Thread starter SFFNetwork
- Start date
This is very much a niche add-on; https://atelieraphelion.com/products/cache-permission-checks.89/Addon link?
Thanks.
This add-on only makes sense if all the following criteria are met;
- A multiple server setup, where the database is separate from multiple front-end webserver
- Redis configured to have a read-only slave on each front-end webserver
- Large numbers of user-groups/node combinations.

I'm curious if your question has been answered. I guess in summary, "It depends".
When you say APC do you mean opcache? PHP 7 should have built in opcache via php-opcache module. Memcache also a great idea. We swapped between redis/memcache, they both did help with performance.

Indeed - if anything I'm a bit more lost given the relative complexity of some of these answers haha
Perhaps folks can share some recommendations. The forum I'm looking to implement caching for has roughly 250k posts and serves ~1M pages each month (to me that's not very much content but a medium level of traffic). We're looking at caching primarily to alleviate some database load where possible, as well as to insulate our site from performance impacts when we have spikes in traffic (which is not too uncommon for us as we are often linked to by other sites, Youtubers, etc.)
From what I can tell, installing memcached or Redis and then configuring contexts with XF to use each is straightforward enough, once I am accustomed to the syntax XF lays out. But I'm getting the impression that there's more to do for more 'optimal' implementations. At the same time, I think something like what @eva2000 listed out earlier is just overkill, and I'm reluctant to introduce a lot of complexity just to eke out marginal performance gain that will not really be appreciated given our size. Finally, I see some difference of opinion on memcached vs Redis but don't know enough about either to have an opinion of my own yet.
Install redis cache*, my redis views & flood checker add-ons is probably an easy & straight forward win. Otherwise additional caching becomes quite complex and more customized.
*A lot of add-ons will start dynamically caching if you have a caching back-end setup.
I prefer redis as it allows me to build more complex solutions, that memcache can't easily address

+1 certainly helps regardless of size of forums as it's a nice measure for when you have unexpected traffic spikes/attacks to have in place anyway
Though then performance will ultimately depend somewhat on the PHP version you use and how it was built PHP 8.0 vs 7.4 vs 7.3 vs 7.2 vs 7.1 vs 7.0 benchmarks

Should have mentioned - we're on 7.4.3+1 certainly helps regardless of size of forums as it's a nice measure for when you have unexpected traffic spikes/attacks to have in place anyway
