It's really hard to generalize about this.  For web apps it's a much more
complex problem.

We have a large number of web servers, very beefy database servers, and run
multiple database slaves handling read queries.  Moving from DBIC to DBI
would make little difference in our case other than in simple benchmarks.
 Plus, scaling the web servers (where DBIC runs) is easy -- and the web
servers are not where our performance issues are, in general.

Caching and sharding is where I'd put my efforts.
