I'm about to buy new server hardware and I was wondering, in your opinion, and reducting problem to one machine (that's it, no more complex network infraestructure in play) what's the local server hardware more important's vector for server performance: memory, CPU, CPU tech, HD space, HD tech.. Where the focus should mainly be pointed at?
Server will be running Debian 10, just Apache 2.4.4 & shell services, and will handle +300 average concurrent clients.
Edited:
Got suggested this post to me as a possible duplicate: How do you do load testing and capacity planning for web sites?
; I wannna clarify that I'm not asking for an actual hardware configuration, not a guide, not load balancing tools to help decissions on upgrades: but for the vector that you'd give priority to give extra air to a heavy loaded standalone apache server (no more services, nor mysql..). The vector you think affects more perfomance on Apache.
I have my own opinion and wanted to hear yours, but I recognize this debate could not be useful for majority, maybe the thread should be closed.
