What are the workload types typically used with s3backer?

[Michael Goddard]

I have an application where I'd like to apply s3backer, and I'm curious whether this has been done successfully.

This is a Postgres DB and, so far, I'm seeing decent performance.  I have been using 2 GB cache files but, since

I anticipate the data size to extend into multiple terabytes, I am thinking to enlarge that value significantly.

Does anyone have anecdotes to share, or suggestions for tuning?

Thanks in advance.
