"Calculating Playback" taking 15-20 seconds Before Playback Begins

After researching this issue, it appears that the problem with Audition is that it was never improved to the point of taking advantage of multi-threading processors. Projects with more than 5-6 tracks start to bog down horribly with hangs of 10-20 seconds after perfectly normal editing actions, combined with pressing play, getting the "Calculating Playback" notification, then waiting 10-20 seconds for playback to begin. Additionally, it's necessary to limit processor-intensive effects like reverbs to only 1-2 instances per project to avoid extremely choppy, bogged-down playback. I have a 9th gen 24 core proc that is hardly working, but Audition was never adapted to take advantage of it's power. I pay a fairly hefty annual fee to use the Adobe suite. I worked for 25 years as a video producer for an institution that paid for everything. Now that I'm retired, it's on me. Is it too much to ask to have an audio production application that is on par with Adobe's other industry-leading apps? When it comes to choosing a DAW, there are a lot of options out there, but I'm paying for Audition. I would like to see a statement from Adobe about the fututre of Audition before I make a commitment to a different company's full-blown DAW. I don't need midi. I just want to mix my sessions without constant grief.
