render very slow

[Tom Daigon]

I have almost the exact same system and had a similar problem. In 6.02 the Hyper threading was not working right with the CUDA. Read this link for a solution that got my Z820 back into the Supersonic speed mode. Look for EC Bownes posts.

Heres a selection of that thread…

I think I have an idea what is going on now. It seems the new update has significantly optimized the Cuda block allocation going on in the background. When I was testing at 16GB of ram I saw far more fluctuation of ram usage going as low as 4GB on the same project that normally pushes 10 to 13GB with all threads active. When all threads are active the ram usage is staying relatively consistent at 8 to 11GB with far less flushing. However with far more ram available it seems the optimizations are triggering some Windows 7 ACPI Power management features that are shutting down cores as not needed even though the actual application really could use the processing to complete the task. Each system board has different ACPI sets that will adjust what Windows 7 does, how, and when regarding power management. This would explain why this is not consistent. This unfortunately is looking like a side effect of optimizations to the Cuda Player Memory allocation and not a bug. Lasvideo you may have to make those registry adjustments after all since this may not be fixable on Adobe’s side.

At the thread Eric provides a solution to the problem that nails it.

Did you try just setting Power Options to High performance?

I have seen this on another app with an ASUS motherboard and Sandy Bridge chips and AMD 7970 gfz running some other app, over 30% slowdown using Balanced Plan…

I see someone else on the thread you refer has the issue even with Power Management on

– Try the same with the nVidia Power Settings (in 3D settings)

Other things to try to see for trouble shooting:

– start a long render and disconnect the monitor cable from the computer (then windows won’t think the screen has not been refreshed for some amount of time…) and see if it makes a difference in time it took to render.

– other troubleshoot idea: set the fan to manual so it’s always on. Run test, any differences… actually this test only works if you can have a previous install to compare against (to see if this slows down the previous version).

– overclocking will require a larger power block

– note: depending on how things are internally implemented you do loose CPU compute power when processing with GPU as there is some thread management involved in controlling the gfx card. It’s much more significative on a quad core then on a 12 cores say I noticed.

– I haven’t tried recently (don’t have dot 0.2 installed) but try to see if there is a difference setting the memory Preferences in Premiere to Favor Memory. This sometimes helped in the past to go faster.

[Pierre Jasmin] “- overclocking will require a larger power block”

HP Z820 are based on the Sandy Bridge EP (Xeon) architecture and cannot be overclocked.

Not just to blame Microsoft, Nvidia, AMD, motherboard manufacturers, Adobe, Apple,… let’s add Intel here.

This is sort of “adaptive” overclocking and will generate CPU variations.

https://www.intel.com/content/www/us/en/architecture-and-technology/turbo-boost/turbo-boost-technology.html

There is some controls for that in Advanced Power Settings panel (and I think it can be turned off to see in the bios, however this should result in stable performance between runs but by slowing it down sometimes).

[Pierre Jasmin]

The gist of my comment is graphic card drivers, os, processors, motherboard firmware,… and applications that do their best to load balance on top of that, and our computers ends up a bit like a microcosm of our power network – oh it’s too hot, every body slows down, oh it’s cold now everybody starts spinning away, oh now using too much power, oh… that is there is not really much work done at the level of coordination of power usage between components of a computer system aside perhaps battery life optimization on small portable devices with closed designs where the parts and standard workloads are known… the focus is all about power savings rather then power management let’s say. It should really be directed by an operating system, I am not an expert but I don’t think graphic cards driver for example pay much attention to ACPI in terms of thermal events… so it could be that HP firmware pays attention on the CPU side so only the CPU slows down even if the gfx card could for that particular workload run the same load with a lower bandwidth (i.e. run at a lower frequency)… which can end up harming the overall performance (i.e. even be faster with the gfx card off). An overkill PSU might help so it never gets above 80% load (so it stays cool and quiet, the firmware communication with ACPI does not see you are peaking usage close to PSU limit… although better ask an EE about that optimal value 80% is a value someone once told me 🙂 ) or some people claim up to up to 20% performance gain with liquid cooling kits – never tried it, but could be an alternative is there is no room for a larger PSU?

[Felix Gorbach] “But when I import 10 bit dpx (720p, 25 fps) rendered files from resolve, the realtimeplayback even in 50% sized window just stucks.”

One thing you might not be doing, though I’m not sure, is to playback your footage at a lower resolution. If you change your program playback from full to half, does that help improve your overall performance?

I ask because changing the window size to 50% isn’t the same as setting the playback resolution to half (50%).

Hy folks – thanks a lot for the tips!

I tried the regedit task – this made sence to me – but it didn´t help. In CPU Usage it´s about 3 to 5 % for my cores all together. No one is making it over this 5%.

I tried to change the power options – to hight performance – still no better result in CPU Usage.

I can understand that the manufacturers of different hardwareparts don`t care about the power consumption of an other device or that the cooling and heat issue nobody of the hardwareproviders cares about.

But I didn´t buy my machine at bestbuy for 400$. I spend in Europe 4750 € for this powerhorse. I bought this machine cause I wanted to eliminate issues like that. When I render in Cinema 4D for example, every CPU goes up to 100% for hours – no issue.

I don´t want to overclock my CPU´s, they are not slow. But Premiere uses them with only 3 to 5%. I`d be happy if premiere would use the CPU power like the other apps like Nuke or Cinema 4D – Full Power, fast – I like it. – but not with premiere – I´m a bit dissapointed.

Is it possible that my hdd is the bottleneck? I don´t had the money to invest in the SSDs.

Does anybody has experience with ssd and the performace with CS6?

By the way, Rendering to RAM Preview in AE – it´s the same – only about 5 to 10 % – and the render (make movie) it´s the same again.

I think I lostt the supersonic speed with CS6.

Sorry that I can´t tell other experiences so far. I can work, the programs don´t crash – that´s fine – and very important as well – but the rendering ist very dissapointing in comparison to other apps.

The Adobe Mercury Playback Engine performs best when CPU, ram, GPU and Media IO (playback of hard drives) is maximized. My Dulce DQg2 has a 1100MB/sec. read and 1000MB/sec. write speed which works together with the other components to get the best performance from CS6.

The regedit fix basically got the Hyper Threading working correctly on my HP Z820, which is based around the Sandy Bridge EP Xeon architecture. What I was experiencing was the lack of the 16 HT working. That fix turned them back on all the time.

Thanks Tom,

Will go through the regedit again to see if I did everything correct.

Thanks so much for your tipps and your time to answer.
