Network latency can make chattiness a problem. More generally I think that not using PL/SQL leads to chattiness and literals. Then parse can become a problem and an expense.
In PeopleSoft that would be close to 100%! I can't think of a practical use of such a ratio. Chatty apps usually aren't instrumented so can't identify chattiest parts.
Perhaps parse is the critical metric?
I was always impressed how well PeopleSoft could perform, given how badly it behaves. No PL/SQL, just a stream of SQL. Often dynamically generated with literals. HR with Time&Labor and Payroll on a pay week was always fun.

Today's gotcha: NB: PLAN_HASH_VALUE on DBA_SQL_QUARANTINE is the adaptive plan hash value (with all of its possible plan alternatives), and therefore it matches SQL_FULL_PLAN_HASH_VALUE in the ASH data, and not SQL_PLAN_HASH_VALUE (the plan that actually executed)! ๐คฆโโ๏ธ
