- touche_bag 2y agoConsistent reads also mean additional checks. I think the WT cache is also very double edged. Completely cripples the database when resource constrained and not sized correctly, while giving a huge boost when the environment is "right sized". Honestly, give 8.0 and tell me how it compares. Haven't touched ancient Mongo versions in a long time, so I have little intuition on how it compares.
