If they're looking at end-user performance issues I'd have the Sybase DBA's check the databases as well. Make sure that they don't need some tuning.

Apache::Session::Lock::Sybase(3pm)			User Contributed Perl Documentation			Apache::Session::Lock::Sybase(3pm)

NAME
Apache::Session::Lock::Sybase - Provides mutual exclusion using Sybase SYNOPSIS
use Apache::Session::Lock::Sybase; my $locker = new Apache::Session::Lock::Sybase; $locker->acquire_read_lock($ref); $locker->acquire_write_lock($ref); $locker->release_read_lock($ref); $locker->release_write_lock($ref); $locker->release_all_locks($ref); DESCRIPTION
Apache::Session::Lock::Sybase fulfills the locking interface of Apache::Session. Mutual exclusion is achieved through the use of Sybase's sp_getapplock and sp_releaseapplock functions. Sybase does not support the notion of read and write locks, so this module only supports exclusive locks. When you request a shared read lock, it is instead promoted to an exclusive write lock. CONFIGURATION
The module must know how to connect to your MySQL database to acquire locks. You must provide a datasource name, a user name, and a password. These options are passed in the usual Apache::Session style, and are very similar to the options for Apache::Session::Store::Sybase. Example: tie %hash, 'Apache::Session::Sybase', $id, { LockDataSource => 'dbi:sybase:database', LockUserName => 'database_user', LockPassword => 'K00l' }; Instead, you may pass in an already opened DBI handle to your database. tie %hash, 'Apache::Session::Sybase', $id, { LockHandle => $dbh }; AUTHOR
This module was written by Oliver Maul <oli@42.nu>. SEE ALSO
