Mnogi korisnici izvijestili su da proces SysMain (ranije poznat kao Superfetch ) uzrokuje veliku upotrebu CPU-a. Iako je usluga SysMain od pomoći u razumijevanju načina na koji koristite svoj tvrdi disk, nije baš potrebna za vaše računalo.

Service Host SysMain uzrokuje visoku upotrebu CPU^{(High CPU)} -a i memorije^(Memory)

Usluga SysMain^{(SysMain service)} je ona koja je povezana sa Superfetchom^(Superfetch) . Njegov je zadatak održavati i poboljšavati performanse sustava tijekom vremena. Nalazi se u mapi System32 . U osnovi^(Basically) , SysMain proces je odgovoran za prikupljanje podataka svake vrste korištenja na sustavu. Zatim se ti podaci reorganiziraju u obliku blokova za vaš tvrdi disk i u skladu s tim daju prioritet.

Ako proces Service Host SysMan uzrokuje korištenje velikih resursa, prije nego što ga odlučite onemogućiti, pokušajte sljedeće:

• Pokrenite Provjeru sistemskih datoteka
• Popravi sliku sustava^{(Repair System Image)}
• Pokrenite alat za čišćenje diska^{(Run Disk Cleanup Tool)}
• Rješavanje problema u stanju čistog pokretanja^{(Troubleshoot in Clean Boot State)} .

Ako koristite HDD na svom sustavu, onda je vrlo vjerojatno da će SysMain uzrokovati visok CPU zbog jednostavne činjenice da se HDD sporo reorganizira. Ako naiđete na problem s visokom upotrebom CPU -a zbog SysMain -a, jasno je rješenje onemogućiti uslugu.

1. Onemogućite uslugu SysMain iz Upravitelja usluga^{(Service Manager)}
2. Korištenje povišenog naredbenog retka
3. Korištenje uređivača registra

Isprobajte sljedeće metode da onemogućite uslugu SysMain^{(disable the SysMain service)} :

1] Onemogućite^(Disable) uslugu SysMain iz Upravitelja usluga^{(Service Manager)}

Najlakši način da se prekine proces povezan sa SysMain je onemogućiti uslugu SysMain iz upravitelja usluga.

1. Press Win+R da otvorite prozor Run i upišite naredbu services.msc .
2. Pritisnite Enter^{(Hit Enter)} da otvorite prozor Service Manager .
3. Pomaknite se prema dolje do usluge SysMain^{(SysMain service)} .
4. Desnom tipkom miša kliknite uslugu SysMain^{( SysMain service)} i odaberite Svojstva^(Properties) .
5. Promijenite vrstu pokretanja^{(Startup Type)} u Disabled .
6. Pritisnite Primijeni^(Apply) , a zatim OK .

2] Onemogućite SysMain^{(Disable SysMain)} pomoću povišenog naredbenog retka^{(Command Prompt)}

Metoda koja uključuje naredbeni redak^{(Command Prompt)} je nešto lakša jer sve što trebate učiniti je kopirati i zalijepiti naredbu.

Potražite "naredbeni redak" u traci za pretraživanje sustava Windows^{(Windows Search)} .

U desnom oknu koje odgovara naredbenom retku^{(Command Prompt)} odaberite Pokreni kao administrator^{(Run as administrator)} .

Zatim u povišenom prozoru naredbenog retka upišite sljedeću naredbu i pritisnite Enter :

sc stop "SysMain" & sc config "SysMain" start=disabled

Nakon što dobijete poruku USPJEH^(SUCCESS) , smatrajte da je posao obavljen.

Ponovno pokrenite računalo.

3] Onemogućite^(Disable) SysMain pomoću uređivača ^(SysMain)registra^{(Registry Editor)}

Urednik registra^{(Registry Editor)} je prekrasan alat za dugoročne promjene u vašem sustavu. Postupak za onemogućavanje usluge SysMain putem uređivača registra^(Registry) je sljedeći:

Press Win+R da otvorite prozor Run i upišite naredbu regedit . Pritisnite Enter da otvorite prozor uređivača registra .^{(Registry Editor)}

Idite na sljedeći put u uređivaču registra :^(Registry)

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SysMain

U desnom oknu dvaput kliknite na vrijednost Start .

Promijenite vrijednost podataka o vrijednosti^{(Value Data)} na 4 i kliknite na OK za spremanje postavki.

Nadamo se da će vam nešto pomoći riješiti problem visoke iskorištenosti resursa^{(High Resource Utilization issue)} na vašem računalu.

Zašto moj host servis SysMain koristi toliko memorije?

Proces SysMain odgovoran je za prikupljanje podataka o svim obrascima korištenja na sustavu. To je usluga povezana sa Superfetchom^(Superfetch) , za održavanje i poboljšanje performansi sustava tijekom vremena.

Je li u redu onemogućiti Service Host SysMain ?

Ne. Ako učitate program, Windows mora kopirati izvršnu datoteku u memoriju kako bi je pokrenuo. Ako zatvorite aplikaciju, program i dalje postoji u RAM- u . Ako ponovno pokrenete program, Windows neće morati ništa učitavati s diska – sve će biti u RAM- u .

Service Host SysMain causing High CPU and Memory usage

A lot of users have rеported that the SysMain process (earlier known as Superfetch) causes high CPU usage. While the SysMain service is helpful in understanding how you use your hard drive, it isn’t exactly necessary for your computer.

Service Host SysMain causing High CPU and Memory usage

The SysMain service is the one that is related to Superfetch. Its job is to maintain and improve system performance over time. It is found in the System32 folder. Basically, the SysMain process is responsible for collecting data of every kind of usage on the system. Then that data is reorganized in the forms of blocks for your hard drive and prioritized accordingly.

If the Service Host SysMan process is causing high-resource utilization, then before you decide to disable it, try the following:

• Run System File Checker
• Repair System Image
• Run Disk Cleanup Tool
• Troubleshoot in Clean Boot State.

If you use an HDD on your system, then it’s quite probable that SysMain will cause a high CPU because of the simple fact that HDD is slow in reorganizing itself. If you encounter a problem with high CPU usage due to SysMain, the clear solution is to disable the service.

1. Disable the SysMain service from the Service Manager
2. Using elevated Command Prompt
3. Using the Registry Editor

Try the following methods to disable the SysMain service:

1] Disable the SysMain service from the Service Manager

The easiest method to kill the process associated with SysMain is to disable the SysMain service from the service manager.

1. Press Win+R to open the Run window and type the command services.msc.
2. Hit Enter to open the Service Manager window.
3. Scroll down to the SysMain service.
4. Right-click on the SysMain service and select Properties.
5. Change the Startup Type to Disabled.
6. Hit Apply and then on Ok.

2] Disable SysMain using elevated Command Prompt

The method involving Command Prompt is somewhat easier since all you would need to do is copy-paste a command.

Search for “command prompt” in the Windows Search bar.

In the right-pane corresponding to Command Prompt, select Run as administrator.

Then, in the elevated command prompt window, type the following command and hit Enter:

sc stop "SysMain" & sc config "SysMain" start=disabled

Once you get the SUCCESS message, consider the job done.

Restart your computer.

3] Disable the SysMain using the Registry Editor

The Registry Editor is a wonderful tool for making long-term changes to your system. The procedure to disable the SysMain service through the Registry editor is as follows:

Press Win+R to open the Run window and type the command regedit. Hit Enter to open the Registry Editor window.

Go to the following path in the Registry Editor:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SysMain

On the right-pane, double-click on the value Start.

Change the value of the Value Data to 4 and click on OK to save the settings.

We hope something helpe you fix the High Resource Utilization issue on your computer.

Why is my service host SysMain using so much memory?

The SysMain process is responsible for collecting data on all usage patterns on the system. It is a service related to Superfetch, to maintain and improve system performance over time.

Is it OK to disable Service Host SysMain?

No. If you load a program, Windows has to copy the executable into memory in order to run it. If you close the application, the program still exists in RAM. If you run the program again, Windows won’t have to load anything from disk – it will all be sitting in RAM.
