EE2 with database caching (via Stash) able to handle traffic spikes up to 100,000 visitors a day?

Hi all,

Since EE2’s database can’t scale horizontally (due to use of MyISAM tables), do you think it would be ok to have 2 - 3 instances of Apache, serving of a single instance of MySQL with 3GB RAM in order to handle traffic spikes of around ~100,000 visitors a day?

I’m using Stash to cache into the database, but should I explore saving pages as flat files for filesystem caching too, since it’s a one-page site with only minimal content management?

Thoughts?

Cheers,
