This is an ill-posed question. perl DBI is faster than sqlplus as a front end. That answers the question.
But. Oracle stores the results of previously parsed queries, which are reused.
So even faster parsing gains you little.
Ok. I've been coding in Oracle since version 2, in 19-um-whatever. I'm older than dirt.
However, SQL code is 85% of performance. Period. Full-table scans instead of using indexes, for example. Reduce excessive disk i/o for queries. All of this is a programmer/application designer problem. Or an exadata problem if you know what that is. Not DBI vs. sqlplus.
Learn to use tkprof. PL/SQL developer. TOAD. Read a Tom Kite book.
The reason you are not getting answers you want is your presupposition:
speed up front = speed in the back end.
It does not work that way - except maybe in special situations - which are usually covered by apps like sqlldr or interesting specialty objects like clustered tables.

apache::session::oracle
Apache::Session::Oracle(3pm) User Contributed Perl Documentation Apache::Session::Oracle(3pm)
NAME
Apache::Session::Oracle - An implementation of Apache::Session
SYNOPSIS
use Apache::Session::Oracle;
#if you want Apache::Session to open new DB handles:
tie %hash, 'Apache::Session::Oracle', $id, {
DataSource => 'dbi:Oracle:sessions',
UserName => $db_user,
Password => $db_pass,
Commit => 1
};
#or, if your handles are already opened:
tie %hash, 'Apache::Session::Oracle', $id, {
Handle => $dbh,
Commit => 1
};
DESCRIPTION
This module is an implementation of Apache::Session. It uses the Oracle backing store and no locking. See the example, and the
documentation for Apache::Session::Store::Oracle for more details.
USAGE
The special Apache::Session argument for this module is Commit. You MUST provide the Commit argument, which instructs this module to
either commit the transaction when it is finished, or to simply do nothing. This feature is provided so that this module will not have
adverse interactions with your local transaction policy, nor your local database handle caching policy. The argument is mandatory in order
to make you think about this problem.
This module also respects the LongReadLen argument, which specifies the maximum size of the session object. If not specified, the default
maximum is 8 KB.
AUTHOR
This module was written by Jeffrey William Baker <jwbaker@acm.org>.
