optimizing disk performance

I have some questions regarding disk perfomance, and what I can do to make it just a little (or much :)) more faster.

Apache::Session::Store::Oracle(3pm)			User Contributed Perl Documentation		       Apache::Session::Store::Oracle(3pm)

NAME
Apache::Session::Store::Oracle - Store persistent data in a Oracle database SYNOPSIS
use Apache::Session::Store::Oracle; my $store = new Apache::Session::Store::Oracle; $store->insert($ref); $store->update($ref); $store->materialize($ref); $store->remove($ref); DESCRIPTION
Apache::Session::Store::Oracle fulfills the storage interface of Apache::Session. Session data is stored in a Oracle database. SCHEMA
To use this module, you will need at least these columns in a table called 'sessions': id varchar2(32) # or however long your session IDs are. a_session long To create this schema, you can execute this command using the sqlplus program: CREATE TABLE sessions ( id varchar2(32) not null primary key, a_session long ); If you use some other command, ensure that there is a unique index on the table's id column. CONFIGURATION
The module must know what datasource, username, and password to use when connecting to the database. These values can be set using the options hash (see Apache::Session documentation). The options are DataSource, UserName, and Password. Example: tie %hash, 'Apache::Session::Oracle', $id, { DataSource => 'dbi:Oracle:database', UserName => 'database_user', Password => 'K00l' }; Instead, you may pass in an already-opened DBI handle to your database. tie %hash, 'Apache::Session::Oracle', $id, { Handle => $dbh }; The last option is LongReadLen, which specifies the maximum size of the session object. If not supplied, the default maximum size is 8 KB. AUTHOR
