Another round of performance optimizations completed

I spent a fair amount of time this weekend optimizing the interaction between NGINX, PHP, Postgres and Cloudflare before I give up on this server and move kbin.run to a more powerful machine. The big change that will improve performance: I'm force rewriting the caching headers on images that are being incorrectly served by Mbin (and /kbin) using Cloudflare page transforms and caching rules... but the underlying problem is something the Mbin team is aware of and will investigate further.

I hope everyone enjoys the boost in page responsiveness now.

Have a nice week!
