I have many checks to analyze with Traktor and the latter only use is one CPU when analyzing tracks despite having activated the multi-CPU support:

Can I force Traktor to use more than one CPU when analyzing tracks?

Using my 12 cores instead of one would help me save some time...:

Rekorbox does it since version 3:

This problem occurs with Traktor 2.6.5.

I've cleaned up the comments here since the Meta question contains most of the ideas. Franck, sorry that your question was missed and not reopened earlier. Are you still looking for an answer at this point? – Matthew Read Jul 16 '15 at 17:58

@MatthewRead Unfortunately, yes, though I fear the answer is that it is not possible :( – Franck Dernoncourt Jul 16 '15 at 17:59

@FranckDernoncourt As of now, it seems that there is no way to use more than one core when analyzing tracks. Kind of unexpected, I wonder what's the reason behind that. – Archundia Jul 16 '15 at 18:55
    
If you find no fix I recommend you report it on the NI forums – Dave Engineer Aug 7 '15 at 8:03

As noted on this page, the solution is to upgrade Traktor to version 2.8.0 or later to support using multiple CPUs during analyzing.

1.4. Parallel Audio Analysis

Also new in this version is a special analysis mode called “Parallel Processing”. This option can be found at the bottom of the Analysis window which appears when you right-click on tracks and choose “Analyze (Async)” from the context menu. If you enable the Parallel Processing checkbox before clicking “OK”, TRAKTOR PRO will then use multiple threads to process many tracks simultaneously. Our tests show that processing a large collection of files can now be done three times faster with this option enabled. Be aware, however, that TRAKTOR PRO will use lots of your computer’s resources to do this and it may affect playback of tracks. We therefore only recommend using this feature in an offline situation rather than during a live performance.
