My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory.

Simply put, compression allows the web server to send smaller files to your web site viewers. When someone enters your URL and requests your site, their browser will indicate to the web server that it understands compression (and which type it understands).
