I’m setting up a server to host busy websites. The best and cheaper option I found is a single processor (4 cores/8 threads) server with 64GB RAM. Of courses this is not very proportional. The services which this server will run will mainly be three: nginx, MySQL and PHP.
However, I found out there’s too much RAM for not enough CPU. I would like some advice. Does nginx consumes a lot of CPU? I know I can tweak PHP and MySQL with accelerators/cache to take more of RAM while saving CPU. But regarding nginx, what’s a good solution?
