Depending on how you configure them, transaction commits usually require your application to perform disk I/O that a non-transactional application does not perform. Also, for multi-threaded <span>and multi-process</span> applications, the use of transactions can result in increased lock contention due to extra locking requirements driven by transactional isolation guarantees. </p> <p> There is therefore a performance tuning component to transactional applications that is not applicable for non-transactional applications (although some tuning considerations do exist whether or not your application uses transactions). Where appropriate, these tuning considerations are introduced in the following chapters. <span> However, for a more complete description of them, see the <a class="ulink" href="http://download.oracle.com/docs/cd/E17076_02/html/programmer_reference/transapp_tune.html" target="_top"> Transaction tuning </a> and <a class="ulink" href="http://download.oracle.com/docs/cd/E17076_02/html/programmer_reference/transapp_throughput.html" target="_top"> Transaction throughput </a> sections of the <em class="citetitle">Berkeley DB Programmer's Reference Guide</em>. </span> </p> </div> <div class="navfooter"> <hr /> <table width="100%" summary="Navigation footer"> <tr> <td width="40%" align="left"><a accesskey="p" href="recovery-intro.html">Prev</a> </td> <td width="20%" align="center"> <a accesskey="u" href="introduction.html">Up</a> </td> <td width="40%" align="right"> <a accesskey="n" href="enabletxn.html">Next</a></td> </tr> <tr> <td width="40%" align="left" valign="top">Recoverability </td> <td width="20%" align="center"> <a accesskey="h" href="index.html">Home</a> </td> <td width="40%" align="right" valign="top"> Chapter 2.
