The reason I am keeping a close eye on resource usage is that our traffic is increasing by around 20% every month (currently over 400,000 page impressions/day although not all of them are search queries!) and I want to make sure we tackle any performance issues before it gets too late. I would rather keep load balancing as a last resort due to cost implications.

Unfortunately, I think that's pretty old stuff. People are normally concerned with: - the number of requests per second they can handle with their server - the average latency of requests (or median, 99 percentile, etc) A goal of reducing CPU usage w/o looking at the other factors is unusual, but if your query rate is very low, or your cache hit rate is low, you could reduce or eliminate caching or autowarming. -Yonik
