Why with the update 22.9.0.36 did not improve performance?

I think you need to give a little more detail about the projects that are giving you problems but it could be that you are using synth plugins which are not part of the load balancing across the cores.

I think it would be easier if you were to list the plugins you are using

you probably already know this, but just to be sure, you must enable plugin load balancing by ticking the box in preferences (sorry can't recall the exact place). i myself have noticed a good increase in performance in sonar platinum since the release previous to this one, (quite amazing in my opinion) and with the latest release that certainly has not changed for the worse

you just enable it once in preferences/audio/playback and recording

Perhaps your performance issues aren't due to CPU usage?

Load balancing doesn't apply to your instruments so if the bulk of your load was coming from them then it may not significantly help.
1. What does your CPU load before and after load balancing look like?
2. What is your audio buffer size in preferences?

Thanks, Noel!
1. Before - It looks like without this update: 1st kernel (core?) is loaded, the other not.
2. 256.

I do not think. The configuration of the studio in the signature.

Load balancing is only going to help performance if unbalanced loads were the problem in the first place.
 
You can test this by pulling up a problematic project with load balancing disabled. If your CPU is running out of steam, and you see that one core is pegged doing all the work, then better load balancing may solve the problem by reducing the load on that overworked first core. Assuming, as Noel notes above, that the plugins placing the heaviest load on the CPU are amenable to load balancing.
 
Bear in mind that not all glitches are caused by CPU exhaustion. If you find that no cores are maxed out regardless of the load-balancing option and there are still dropouts, that may indicate that the real problem is with a hardware interrupt handler.

my cores used to be very balanced in many projects even before load balancing - because Sonar had multi-processor support before and when using similar plugins across many tracks

 sonar229030
 sonar229036
It is one and the same project.
 

if you only have 1 FX per bin, you wont see a dramatic effect on Core usage.

Bear in mind that not all glitches are caused by CPU exhaustion. If you find that no cores are maxed out regardless of the load-balancing option and there are still dropouts, that may indicate that the real problem is with a hardware interrupt handler.

Thank you, bitflipper. I understand it.

Thanks for the animated screenshot, Vyacheslav. A picture is worth a thousand words.
 
As you can see, load balancing really did spread the load across the cores, and the first core isn't nearly as busy in the "after" picture. However, even in the "before" picture, the first core is nowhere near maxing out.
 
A CPU is either capable of handling the current demands or it isn't - it's not like a human, who benefits from a lighter workload even if he isn't being pushed to the limit. As long as the CPU can keep up, you'll experience no subjective difference between the before and after scenarios, which is exactly what you noted.

First things first: Clarify the symptoms. What does "glitches in projects" mean, exactly?
 
If it means crackles/pops on playback, that could be due to high DPC Latency which will not show up in Perf Meters.

And how does your slave computer figure into your system?

This so-called server for Vienna Ensemble Pro5.

Yes, this crackles/pops on playback. Infrequently, rarely.

If there's no change in performance when you adjust everything else, maybe your issues could be hard drive related? I can't see it very clearly on my phone, but you hard drive meter seems to be getting up there. Just a tought.

Thank you, pinguinotuerto. But the same glitches occurred with less filled disc.

Then more reson to investigate the drive.

 
This CD is in perfect condition - Seagate Desktop SSHD ST2000DX001.

I noticed you're using sample based VSTis. Don't those require disc reading? Do you have them on the same drive as SONAR? Sorry but I'm on my phone so I can't see your system specs.

It could also be an issue related to the graphics card + plugins and VSTis that have processor hungry GUIs.

Thank you. I understand it. I am sure that is not the case.

Sorry, I didn't understand that response. What do the numbers look like?

 OK! It?

Also, do you still have problem if you shut down the client component of the Vienna server system on your main DAW?

Sometimes.

I'm not familiar with this system, but it sounds like a rich source of potential problems that I would want to rule out first.

Problems may be (or not may be) and with the Vienna Ensemble Pro and without it. )) But steady work of Vienna Ensemble Pro (as well as sonar) depends on the plug-in in it.

Hi Vyacheslav,
I also rely heavily on Vienna Ensemble Pro in my setup.  I ran several tests today on the latest version of SONAR (22.9) and could find no performance hit from previous versions.  VEP is so lightweight - since it moves the heavy-lifting to the other server(s) - that it took a lot just to get it to register a few percent CPU load overall.  If you suspect that VEP is a problem with your SONAR performance can you try narrowing it down and post a project that I could try?  It'll be next to impossible to replicate your setup, but we might be able to pin down the issue if there is one.
Thanks!

Thanks, Bob! I did not say that I have a drop in performance occurs when using the Vienna Ensemble Pro. I said that with the new update (22.9.0.36-41) increase in performance did not happen.

Noel Borthwick [Cakewalk]
If so that probably indicates that your glitches are not CPU load related but caused by something else.

May be. As like as not. Like enough. )) Forgive me for my english. )
