I know this is a question that's going to have some very general answers, but I'm hoping for some specific examples:
If one were using a CDN and effectively caching pages, where would you say the upper limit of traffic is on a basic shared hosting account using something like BlueHost, DreamHost or Mediatemple.
Could it conceivably handle say, 100k users per month? Or is that just impossible even with caching and something like CloudFlare?
ps: Please don't recommend dedicated Wordpress hosting sites. That's not what I'm asking about.
