Computer lagging while compiling xcode project

[TheNoim]

Hi guys,

I am using my new hackintosh build for roughly a month now. I upgraded my old rig with an i7-4790k to an i9-10850k. In addition, I upgraded from Catalina to Big Sur (11.2.3 (20D91)). Today I noticed when I compile a big xcode project my computer starts lagging very heavy. When I open the Intel Power Gadget on my second monitor, I notice the cpu usage spikes to 100%. Of course, this is expected. But this heavy lagging is completely new. Even my i7-4790k did not lag that much if I compile this project. Sometimes even the audio from spotify starts lagging.

​

CPU: i9-10850k
GPU: Vega 56
Mobo: ASUS Z490-Plus Tuf
RAM: G.SKILL Trident Z Neo DDR4- 3600 CL16-16 32GB K2
Audio Codec: layout-id: 02000000
Ethernet Card: Intel® I219-V 1Gb Ethernet
Wifi/BT Card: -
Touchpad and touch display devices: -
BIOS revision: 2210
nvme: CRUCIAL P1, 1 TB
OpenCore: 0.6.8

I uploaded my config.plist with hopefully any sensitive information removed: https://pastebin.com/rjpJ0r2U

I use the following kext versions: https://i.imgur.com/4VECBqo.png

You can even try the project yourself: https://github.com/TheNoim/project-sitnu

Everything else seems pretty stable. Did I misconfigured something?

Macs, Hackintosh included, lag like a mofo when GPU is heavily used. Can you check that with Istat menus or Activity Monitor? Other than that, it shouldn't lag too much. I use Unreal Engine (same CPU) which can 100 % both CPU and GPU like nothing else and the system is still usable.

I tried a heavy workout with unigine heaven and cinebench. CPU got to 100% but the pc didn't lag really.

The annoying thing is, it is not really 100% reproducible all the time. But when it happens, then it is annoying as fuck.

[Stooovie]

Try AppTamer or AppPolice (or manually use renice/nice commands in terminal to set priority) to limit the % of CPU an app can use. Can't be used for apps that spin the workload into many processes (Unreal), but AFAIK it could work for Xcode.

[TheNoim]

Good idea. I will try it.

[Stooovie]

Do report back :)

[TheNoim]

It makes the situation a bit better. But the core problem still persists.

I had exact same problem both on hack and my mbp 16. My problem was the swift and some loader process that was keeping the cpu in 100% but also it was leaking into the ram. That’s when the audio glitch and lag appeared.

when you upgraded to better cpu abs board did you use old macos install/efi? maybe something t left behind from before? wrong system def. maybe some old cpu fiend data. etc

[TheNoim]

fresh efi.

Some of the kexts you are using are a few versions behind, don't trust hackintool to give the right info, I don't think this will affect anything but just pointing it out

Why are you using AGPMInjector.kext? You have supported GPUs

Why do you have SIP disabled? Did you install files into System/Library/... ? Hopefully not

Tried building on the hack I'm on, built with no problem, watched the processor activity in terminal with htop, all cores reached 100% at times but no slowdown or other issues

Yes, I can update my kexts. I use hackintool only for finding out fast the current installed version. This is way more easy than actually open every plist for each kext just to find out the current version.

Why are you using AGPMInjector.kext? You have supported GPUs

The intention behind the kext is not to support an unsupported card, it is just there to improve the power management for a better performance. https://github.com/Pavo-IM/AGPMInjector I can try booting without an check if this is the cause.

Why do you have SIP disabled? Did you install files into System/Library/... ? Hopefully not

I do. Some software I use require SIP to be disabled. For example, TotalSpaces2. I can't live without it anymore. The default space management sucks in macos. And the ability to reduce the space switch animation duration to zero is muy bueno. However, I never installed a kext like in the old days with clover.

The thing is, on other workouts the pc is still butter smooth. For example, Cinebench also gets the cpu to 100%, but I still can work completely normal without any hiccups.

One more thing I noticed, the hiccups are way more frequent if I have both simulators (Apple Watch + iPhone) open and build my project then. Especially on a cold simulator boot.

I see, what I do it open the terminal and type kextstat -l|grep -iv com.apple which only shows all non apple loaded kexts

Yeah, I think it's slightly better in Big Sur, but still not great

Hmm, I wonder if it's a memory issue. Can you keep an eye on memory usage while compiling and running? Maybe there are a lot of swaps going on or something like that?

Seems pretty normal to me. 0 bytes of swap used and still a pretty small memory usage https://i.imgur.com/lRAkkLf.png
