You can try to prove this hypothesis by adding an external 1GbE adapter. I’ve done this for all of my players and things don’t improve much at all.
Even SC6000Ms using fast internal SSDs with all non-essential services turned off have serious UI jank issues. The network speed is part of the problem, but the majority (imho) is the speed in which the SoCs operate and what is being asked of them.
Isn’t the speed of USB 3.0 ports partly the limiting factor here?
Internal SATA is also limited to 500 MB/s anyway.
USB 3 speed is between 5Gbps and 20Gbps.
Internal SATA is converted to USB 3 on the main board.
I had no idea that the internal SATA adapter is actually driven by USB. Thank you for sharing that.
Al that talk about being independent is a bit awkward if this pops up a couple of days later: Digital DJ Tips
It’s ok Ben, plenty of people in the comments asking why it’s not for the brand formerly known as Pioneer to rebalance again.
totally agree!!!
Correct statement. I think the fact that the decks are limited to a small set of DJ software is the only disadvantage, i.e. I can’t use Traktor :((. Otherwise, only (very) good!!
You can use traktor. Computer mode sends midi data over usb, just map the decks in tractor and go. Nothing stopping you there.
Great.I will try…
Hello again. I tried but it doesn’t work. Have you tried it or is it just a general idea that SC6000 can be mapped as midi in Traktor? If so, how is it done because I’m not that advanced in IT, I’m just a good DJ 
I did map SC5000, and SC6000 works exactly the same. You just need to map it in controller manager.
Use a cdj3000 and you will understand why sc6000 needs cpu and memory upgrades.
No real new Denon unit since 2019 !
Some people say the SoC in the CDJ-3000 is slower than the 2014 SoC in InMusic devices 
Are you saying that The CDJ3000 has blast processing?
“Pioneer Does, what DenDon’t”
- be really specific
“or else whatever you posted is totally not valid” - or whatever.
Anway…
Good points. I would love to see top priority on these before anything else (including Stems). There is always the infamous “various bugfixes and improvements” bullet point we can see for new software releases, which is good, but at least in terms of UI-response snappiness and loading/buffering times, I haven’t noticed any significant improvements since 2.x. if I am honest. To be clear, it’s not terrible, but the overall solid experience and sleek-looking GUI gets spoiled by a stuttery encoder or scrolling response and temporary freezes (music keeps playing) of the display and LEDs when loading longer songs / mixsets, or using the << / >> track skip buttons repeatedly. And yeah, the boot-up sequence time is pretty slow.
The CDJ-3000 is underpowered in terms of functionality, but it probably has a newer SoC which has to do less, so the essentials it does, it does quite well.
In other words: Our SoC (RK3288) is from 2014 and was already in the low-mid tier back then. SC5000 and MPCX were released in 2017. Still were awesome, partially because the competition (e.g. Pioneer, Roland) cheaped really out on their CPU and RAM (probably in the 64-128MB range). But in 2025, the ecosystem (Denon, Numark, Akai, maybe also Rane in future) would greatly benefit from a stronger chip and at least double the base RAM, especially for the MPC/Force devices with the beefy plugins/synths. Since the base OS takes about 1GB of memory, going from 2GB → 4GB alone would triple the breathing air for everything else.
Maybe we get the RK3588 from 2022? That would be a promising upgrade. A more cost-effective compromise would be the RK3576, but it was released in early 2024.
I use CDJ3000 almost every weekend, and I can tell that these decks are slow and have a lot of issues. They do basics good, but when you start throwing more processing on them, they do have issues. Stuttering screen, slow list loading, long time buffering, issues with reading usb’s and some tracks, to name a few. Not mentioning that our CDJ3000’s were already 6 times in service for multiple issues like unresponsive buttons, broken power supply, jog wheel detecting pressure without pressing the jog wheel, broken usb jack, broken master tempo button, etc… cdj;s are not as robust as they were before…
Thank you for sharing this. I thought this was exclusive to the Denon gear. 
2 weeks ago we had a show at the club where we had a bunch of djs. Cdj’s just went to emergency loop at every second track. One deck froze completely. Luckily we had 4 cdjs on hand. So we managed the situation. But on top of the recent issues - crush and space buttons broke. There was no way to activate these 2 effects. Not mentioning how sloppy it was on reading the bpm over the pro dj link. And yes, we installed latest software on all decks and mixer.
See, seems Pioneer is falling into the same rabithole of “hardware first, then think about firmware”….
I personally think a lot of us have a firm memory of how CDJ1000s worked. And they where pretty much rock solid. But so where Denon twin players. I have only used the CDJ2000 in HID mode, controlling Traktor… And a CDJ3000 I even still have to encounter in the wild (really!)….
Oh, and I totally forgot I owned 2 CDJ900s for some time, when Rekordbox was all new and shiny: pumped my 20.000 track collection onto a USB stick. And guess what, when searching, more or less 10 seconds passed with each entered character. Thats beyond completely useless for my use (8 hour sets where the genre to be played is function of the crowd I’ll encounter). So these CDJs where used in HID mode from then on, until the CDJ2000 became mainstream (took about 2 years). And if I remember correctly, the function where you connect a Rekordbox laptop via ethernet to your players only came into play after I sold these CDJ900s. Or was it a licensing issue? Cant remember for sure…
So no, Pioneer is not all unicorns and rainbows. Neither is Denon. But, given I wanted to ditch that stupid laptop in front of my face, Denon suits me better…
