Is the NEW Lightroom Classic CC FASTER? Speed Test + Side by side comparison

Welcome to our latest blog post where we dive into the performance upgrades of the new Lightroom Classic CC. As photographers, one of the biggest challenges we face is the time it takes to edit and manage our vast collection of images. Adobe claims that the new version is faster and more efficient, but is it really true? In this post, we will conduct a thorough speed test and a side by side comparison between the previous version and the new Lightroom Classic CC. Join us as we unveil the results and determine whether this upgrade truly lives up to its promise of increased speed and efficiency.

Is the NEW Lightroom Classic CC FASTER?

Speed Test + Side by side comparison

Hey everyone, we have some exciting news this week as a’dope has released the new Lightroom Classic CC, which replaces the old Lightroom CC that we have all been using. A’dope claims that the new Lightroom Classic CC has better performance, allowing you to import photos, generate previews, and move from Library to Develop mode in record time. In this article, we will test these claims and compare the speed of Lightroom Classic CC and Lightroom CC side by side.

Import Speed Test

First, let’s start with the simplest test of all – importing an entire wedding photo collection. We will time the process to see the difference between Lightroom Classic CC and Lightroom CC. In this head-to-head race, we will import 3,886 photos into each catalog simultaneously.

Previously, we would import only the final selected photos from a wedding, which would be around a thousand images. However, with the new capabilities that a’dope claims Lightroom Classic CC has, we can now import all the photos we shoot and cull them within Lightroom itself, eliminating the need for third-party applications like Photo Mechanic or Adobe Bridge.

This test is being run on a full gigahertz i7 5K iMac with 16 gigs of RAM.

Results of Import Speed Test

The results of our import speed tests are as follows:

  • Lightroom Classic CC: 5 minutes to import all the photos, an extra 9 minutes to render all the preview files, totaling 14 minutes and 13 seconds.
  • Lightroom CC: 3 minutes and 22 seconds to import files, 10 minutes to render previews, and an estimated additional 15 minutes of rendering, totaling 28 minutes and 22 seconds of importing and waiting time.

The reason why Lightroom CC was faster in importing the initial photos compared to Lightroom Classic CC is because the Classic version renders previews while importing, making the whole process more efficient. Additionally, Lightroom Classic CC is significantly quicker at processing previews, taking only 9 minutes compared to 22 minutes in the old Lightroom CC.

Improved Image Navigation

One of the key areas where Lightroom Classic CC has improved is in image navigation. We compared how fast it is to flick through images in Lightroom via the library panel in real time. As you can see, the speed has vastly improved in Lightroom Classic CC. Even though it took Lightroom CC half an hour to render previews, it still needs to load each image as you press next, unlike Lightroom Classic CC, which has no loading time between images.


In conclusion, the new Lightroom Classic CC is significantly faster in importing files and offers more efficient image navigation without any loading time. Applying presets and viewing before and after previews has also been vastly improved. This major upgrade to Lightroom promises a less laggy version for editing photos. Many users, including the author of this article, are looking forward to using this improved version going forward.
