It's not all that out of the world. Consider how many distinct objects
need to be fetched to generate a single page. If your caching model
caches individual objects, you could easy have 200 or more per page.
6 million / 200 = 30,000 Page views per second.
Maybe thats high, maybe its not, but it doesn't seem out of this world
to me.
For Bloglines, we commonly have pages that will do 200 to 1000 object
fetches from memcache. Getting to 6 million+ aggregate memcache
requests per second is definitely feasible.
I hope you're doing a single multi-get or say a handful of them, rather
than actually 200 to 1000 DIFFERENT CONNECTIONS. I don't think Steve
separated each object from within a large multi-get request when saying
that some of his nodes do 30-60k reqs/s, maybe he did? ...
