# Which 3D parts catalog systems maintain fast performance even with thousands of models loaded?

<a class="a a--md" elv="true" href="https://www.g2.com/products/components-engine/reviews"><strong>Components Engine</strong></a><strong>:</strong> Reviewers specifically describe the viewer as incredibly fast even with complex machinery containing hundreds of parts, loading in seconds and performing well on both desktop and tablet.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/3d-contentcentral/reviews"><strong>3D ContentCentral</strong></a><strong>:</strong> Occasional lag is noted specifically when loading larger files, which is worth factoring in if your catalog leans toward heavier, more detailed models.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/cds-visual/reviews"><strong>CDS Visual</strong></a><strong>:</strong> Server response times are described as occasionally unpredictable, though generally manageable, for catalogs with a large number of configurable products.</li>

&lt;p&gt;The threshold question is really about whether the viewer loads the whole assembly or only what&#39;s on screen. A catalog of ten thousand models is fine if each page pulls one lightweight mesh; the lag shows up on the single 3,000-part machine where the viewer tries to render every fastener at once. So a system can be &quot;fast with thousands of models&quot; and still choke on your one biggest product, so worth testing with your heaviest assembly, not your typical one.&lt;/p&gt;
