I think, If you are looking for the best infrastructure in this segment, 100% Vultr High Frequency (HF) is the way to go.
When it comes to running Discourse, single-core processor performance is what matters most, and Vultr HF absolutely dominates here with their 3GHz+ CPUs. It makes a massive, noticeable difference in how snappy the forum feels.
I’ve been using Vultr HF for years, and I haven’t run into a single issue. It just works great.
