<h1 align=center>Release 3.1: log file pre-allocation</h1>
<p>This change only affects Win/32 applications.
<p>On Win/32 platforms Berkeley DB no longer pre-allocates log files.  The problem
was a noticeable performance spike as each log file was created.  To turn
this feature back on, search for the flag DB_OSO_LOG in the source file
<b>log/log_put.c</b> and make the change described there, or contact
Sleepycat Software for assistance.
