<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="../../../implementation_strategies/io_adapter/memoryioadapter.html" class="wikiLink">MemoryIoAdapter</a></i>
- improves the insert performance, by replacing disk access with memory access:</p>
<span name="cs_wiki_filter" csw_filters="net">
<p>.NET:</p>
<p><code>configuration.Io(new MemoryIoAdapter());</code></p>
</span>
<p><i><a href="../../performance_hints/no_lock_file_thread.html" class="wikiLink">lockDatabaseFile</a></i>
- reduces the resources consumption by removing database lock thread. Should
only be used for JVM versions < 1.4</p>
<span name="cs_wiki_filter" csw_filters="net">
<p>.NET:</p>
<p><code>configuration.LockDatabaseFile(false);</code></p>
</span>
<p><i><a href="../../performance_hints/turning_off_weak_references.html" class="wikiLink">weakReferences</a></i>
- switching weak references off during insert operation releases extra resources
and removed the cleanup thread.</p>
<span name="cs_wiki_filter" csw_filters="net">
<p>.NET:</p>
<p><code>configuration.WeakReferences(false);</code></p>
</span>
<p><i><a href="../../performance_hints/flushfilebuffers.html" class="wikiLink">FlushFileBuffers</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>
<span name="cs_wiki_filter" csw_filters="net">
<p>.NET:</p>
<p><code>configuration.FlushFileBuffers(false);</code></p>
