The amount of caching I see in a Rails app is inversely correlated to that app's performance. My theory is people use it to band-aid over bad SQL, and it never works.
@nateberkopec in that regard i find that ORMs are hurting perf (and quality) because „nobody“ knows SQL and DB modelling.
@nateberkopec I wonder how many hours of gnashing could be alleviated by scaling up the DB server. After all, the database server has its own cache which is quite smart, as does the operating system. 😁
@nateberkopec usually it works in the beginning, giving you false sense of relief and then it got even worse.
@nateberkopec I switched our app over to Phlex which just plain doesn’t work with fragment caching. I had to preload here, add an index there, generally fix things up instead of just going “meh, it’s all cached anyway.” App feels a little better for it but I gotta say I miss the lightning-fast cache hits for some pages
