Over at Web Performance there is a well written blog post about issues one must be careful of when doing load testing from Amazon’s cloud. The major issues that didn’t seem to have obvious fixes in the article were:
CPU Utilization
High CPU usage can cause timing delays in page durations, skew the distribution of users as the load is ramped up, and slow down page processing (particularly extractors using regular expressions).
Bandwidth
Amazon and other cloud-computing services either do not guarantee a level of bandwidth, or guarantee a certain amount of bandwidth rather than a level.
