1. Set performance benchmarks

Make sure your goals are realistic. Tip: Look at your competition.

2. Review analytics data

Identify peak hours of traffic within the last year. Tip: Figure out the maximum using analytics then go 10-50% above that peak number in order to ensure you have needed bandwidth for potential spikes in traffic at any given time.

After testing make sure you review the results and align them to your timelines. it's important to analyze across all of the areas and make sure you don't look at the results in isolation.
