The most important goal is reliability, then speed.
Speed above everything
Avoid microservices Perhaps there is way to make these work but I haven’t achieved it yet.
Keep track of your bottlenecks Blot involves lots of i/o, like reading ﬁles from a disk or syncing a ﬁle over a network. Because of this, most of what really needs to be optimized is i/o. Nothing is especially computationally intensive. Shaving even one external HTTP request from a function will save inﬁnitely more than endless language-level performance optimization.
Speed above everything. I run almost everything send to the client through as many miniﬁers and compressors as is reasonable. I want to improve the speed of Blot. I also use a neat script called instant.page to begin fetching a page when the user hovers over a link.
