Grep the lemmy server code for “= LocalSite::read” - and I find that even for a single vote by an end-user, it is doing an SQL query to the local site settings to see if downvotes are disabled.

Can some Rust programmers chime in here? Can we cache this in RAM and not fetch from SQL every time?

PostgreSQL is telling me that the 2nd most run query on my system, which is receiving incoming federation post/comment/votes, is this:

SELECT "local_site"."id", "local_site"."site_id", "local_site"."site_setup", "local_site"."enable_downvotes", "local_site"."enable_nsfw", "local_site"."community_creation_admin_only", "local_site"."require_email_verification", "local_site"."application_question", "local_site"."private_instance", "local_site"."default_theme", "local_site"."default_post_listing_type", "local_site"."legal_information", "local_site"."hide_modlog_mod_names", "local_site"."application_email_admins", "local_site"."slur_filter_regex", "local_site"."actor_name_max_length", "local_site"."federation_enabled", "local_site"."captcha_enabled", "local_site"."captcha_difficulty", "local_site"."published", "local_site"."updated", "local_site"."registration_mode", "local_site"."reports_email_admins" FROM "local_site" LIMIT $1
