I played manually the E-major. Here is the result:

  • 43.2% average. 45.3 max (i7-4810MQ@2.8GHz) Null Audio/256
  • 42.1% average. 44% max. same processor. Audio Board ASIO/256

I’m unable to reproduce your “19%” conundrum.


I expreminented the same thing…
Stop and reopen and you win some extra %… well I saw that too.

I tried Torsten’s “perftest” song file, with null audio @ 44.1 / 256

Average time load - 68.0%
Maximum time load - 89.4%

I’m using a 10 year old 1st generation i5-750 @ 2.67GHz 4 core desktop.
Ya I know it’s antiquated, but has been reliable. And actually survived (barely) this test. :slight_smile:

I did not experience the load % changing after stopping and starting the audio engine like Torsten experienced.

I got better performances in aggressive mode. Not so much as you. About 8%

still better :slight_smile: than nothing

I made new test with the same parameters.

Surface pro 2 i5 70% 75%
Surface pro 3 i7 68 % 78%
Surface pro 7 i5 1035G4 48% 60
Dell inspiron i7 8565u 43% 50%
Pc (2014) i7 4770k 42% 45%

This is not directly related to your search for an older system, but I thought I’d mention that early this year I went through an exercise of trying to find a powerful laptop to handle a live VST/etc. laptop. I tried a few “loaded” consumer laptops in sequential order because none of them worked for me and I had to return them as I tried them. Yoga, Thinkpad, Dell. I selected the most current/powerful/fast CPU, 32GB, dual SS drives, etc. The only thing I didn’t spend on was the graphics/monitor. All of the laptops I tried had audio cracks & pops to some unsatisfactory degree. Even if I got a small glitch every 5 minutes, I considered it a failure. I performed all sorts of tuning, cleaning up, … nothing helped. I read, and was told, that the laptop power management (due to having to manage battery power) got in the way of clean-performance, … and that I should try a Clevo chassis (or any other “gaming laptop” type chassis). I ordered one (which did cost 30% more than the consumer laptops). I have not had any glitches at all on my current laptop and am extremely happy with it.
What I run “live” on the laptop:

  • 2 instances of standalone NI Kontakt (keyboard VSTs for 2 keyboardists)
  • Cantabile, which runs 3 instances of NI Guitar Rig in stereo. This results in 3 vocalists having 6 channels of plugin-effected vocals. Also an occasional Waves Tune Real-time “auto-tune” plugin.
  • ShowBuddy Lighting software
    *** Both Kontakt and Guitar Rig interface to a QSC TouchMix-30 digital mixer

Hi @Torsten

I’ve had reports of this from some users before but never been able to reproduce it myself. Also never heard of it with the Null Audio driver, but I guess that’s rarely used. Leave it with me I’ll do some tests in the next day or two.

In the meantime it’s probably worth running a CPU reporting tool to see if any of the cores are being throttled or parked before vs after.


Hi guys,

I’m on an i9 7700x @ 3.3 GHz (10 cores - HT Off) and hit around 33% not quite the heights one would expect to hit over a lot of the i7s but does show that it’s not necessariy the number of cores that gives you the performance…

Cheers, and thanks to @Torsten as always.


It seems there are very different experiences, and a few processors to evaluate. I’m about to gather our posts to create a small database. I think I’ll use an Excel sheet, in old .xls format (Office 97-2003). So, it will be compatible with G-docs, OpenOffice and more. Here’s a possible screenshot. Any feedback will be appreciated.
In the meantime, I’d like to see more test like the one @Torsten proposed.

More cores can help. The most important parameter is the frequency. The higher GHz the better.That’s why desktop win on laptop.

That is my desktop… :wink:


At now, yes :thinking:

A great way to understand the performance of a processor is a parameter called “thermal design power” (TDP). Hereby the PC’s typical values:

  • Ultra portable PC (fanless) : 5W
  • Portable PC : 15W
  • Gaming PC and Mobile Workstation : 45W
  • Desktop PC : 65 to 95W
  • Desktop workstation and server : 95 to 250W (and more)

Although the relationship between TDP and performance is not linear, surely the higher TDP the faster PC

Another (@torsten) test. Sorry, the result is really funny, so I posted here.

  • 22.1% average. 27.7 max (i7-7700HQ@2.8GHz) Null Audio/256

Well, it’s a MSI gaming laptop, but I think there is something wrong in this result. Time Load is too low. Using my typical test configuration (sampled piano + convolution reverb) I get 10% average. Same test on my older laptop (4th gen. i7) result is about 16% average. Both these PCs are heavily tweaked, I spent days trying turning windows-services off. The wifi is uninstalled, Antimalware is off, same for firewall, indexing, and lots of other services.
@brad, Windows 10 installed in the gaming pc is version 2004. I tried to set the core parking, I set to 0 the right parameter in right keys, but in the power plan i see Min. speed and Max. speed. After the update, core parking is disappeared. Any hint?

Lenovo Thinkpad T590
I7-8565U @ 1.8 GHz

I have it optimized with “the instructions” plus I kill all of the Lenovo services when I start doing music studio stuff.

I am seeing Time Load values from 37.4% to 43% usually with quick spikes to 50%+.

With your msi laptop you get the best results!
Is it because the processor is named HQ ?

No, I guess there’s somewhat error I can’t understand. 22% is definitely an impossible value. I’ll delete the test from the file.

If anyone wants to test his/her PC, please send me the result (or post here), I’ll update the list.

  • 52% average. 91% peak (Ryzen 5 2500U@2.0GHz) NullAudio/256
    AMD Ryzen 5 2500U is (sadly) a not so efficient processor. It can be compared to a underpowered 7th series mobile Intel i5. 3500U is better, but still lacks of performances. Only the brand new 4xxx models are on same level of a 10th gen intel, sometimes better.
