gollark: Also, praise SQLite, as it is GOOD™.
gollark: This is weird, I'm testing the performance of this at larger scales by using the API and some shell scripting to (sequentially) insert 10000 pages, and requests usually take about 8ms but randomly spike to a few hundred occasionally.
gollark: <:bees:724389994663247974>?
gollark: Pretty much all of the algorithms reduced size by ~50% or so and the difference is maybe 5% or so between them all, so this is definitely premature optimization, but bees?
gollark: I tested four different compression algorithms and brotli did fairly well; I would have used zstandard but the node bindings for it are awful, and brotli actually did do better on small inputs.
