Even for a twitter recommendation engine, that's just a lot of moving parts.
I hope your development is driven by accurate profiling and benchmarks. It's much better to have a dirty, but very surgical fix in a specific bottle-neck, than to have your application "scaled" with too many layers of individually "optimized" components, that bog each other to a crawl when combined.
- timhastings 16y agoThere are a lot of moving parts, but these are separate sub-systems with well defined boundaries of interaction. Each sub-system is implemented using technologies selected for specific characteristics. Mono for long-running and complex backend processes. nginx, PHP, MySQL, memcache - for presentation - quick! node.js provides an event bus between PHP and Mono MongoDB is taking over from storing large blobs of JSON in MySQL.
- mahmud 16y agoMakes sense. I was on the opposite side of things, when I did we last. I had language integrated into the web server, and I wrote my own caching primitives. All optimization went into the request handler, and optimizing a single function is easier than debugging a whole stack. A decent solution, but it had no massive inputs, so I slept better at night knowing it wasn't being tested.
