Scalability is more than benchmarking a specific operation. Are you trying to do 200 writes to a single row transactionally? App Engine (and honestly, very few other systems in the world) will not meet your needs. Are you distributing 200 writes across various keys, randomly spread out across the entire keyspace? You'll probably be fine.
You'll need to provide a more useful description of what it is you plan on doing to get a useful answer. I find this blog post to be great in describing the differences between scalability and benchmarking. It's about node.js and non-blocking I/O, but the concepts apply in general: http://al3x.net/2010/07/27/node.html -- Ikai Lan Developer Programs Engineer, Google App Engine Blogger: http://googleappengine.blogspot.com Reddit: http://www.reddit.com/r/appengine Twitter: http://twitter.com/app_engine On Thu, Feb 10, 2011 at 8:42 PM, Atif Gulzar <[email protected]> wrote: > > Yes I can run the load runner tools.
