<h1>Configuration Options</h1>
<p>Configuration options can also affect the insert
performance. Some of them we've already came across in the previous topics:</p>
<p><i><a href="../../../configuration/file/storage/memory_storage.htm">MemoryStorage</a></i>- improves the insert performance, by replacing disk access with memory access.</p>
<p>
<p><i><a href="../../../configuration/file/lock_database.htm">lockDatabaseFile</a></i>- reduces the resources consumption by removing database lock thread. Should
only be used for JVM versions < 1.4</p>
</p>
<p><i><a href="../../../configuration/common/disable_weak_references.htm">weakReferences</a></i>- switching weak references off during insert operation releases extra resources
and removed the cleanup thread.</p>
<p><i><a href="../../../configuration/file/storage/nonflushingstorage.htm">NonFlushingStorage</a></i>- switching off flushFileBuffers can improve commit performance as the commit
information will be cached by the operating system. However this setting is
potentially dangerous and can lead to database corruption.</p>
