Općenito, propusnost je brzina kojom podaci putuju tamo-amo s vašeg računala. Drugim riječima, širina pojasa je raspon pokriven za prijenos podataka između gornjeg i donjeg raspona. Propusnost^(Bandwidth) obično kontrolira vaš davatelj internetskih usluga^{( Internet Service Provider)} ( ISP ). Međutim, postoje neke postavke u sustavu Windows^(Windows) , konfiguriranjem kojih ograničavate rezerviranu propusnost za svoj sustav.

Prvenstveno, Windows rezervira određenu količinu propusnosti za svoje zahtjeve aplikacije i operativne svrhe. Konfiguriranjem njegove postavke u Pravilima grupe^{(Group Policy)} možete jednostavno ograničiti rezervisanu propusnost. Ovaj će vam članak postupno pokazati kako pristupiti ili otvoriti rezerviranu propusnost na vašem Windows 11/10/8.

Ograničite postavku propusnosti koja^{(Limit Reservable Bandwidth Setting)} se može rezervirati u Windows 11/10

1. Pritisnite kombinaciju Windows Key + R , upišite put gpedit.msc u  dijaloški okvir Pokreni i pritisnite ^(Run)Enter da otvorite uređivač lokalnih grupnih pravila^{(Local Group Policy Editor)} . Usput , uređivač grupnih pravila^{(Group Policy Editor)} nije dostupan u verziji Windows Home . Dostupan je samo u verzijama Windows Pro^{(Windows Pro)} , Enterprise itd.,

2. Idite ovdje:

Computer Configuration -> Administrative -> Network -> Qos Packet Scheduler

3. U desnom oknu ovog prozora potražite postavke pod nazivom Ograniči propusnost^{(Limit reservable bandwidth)} koja se može rezervirati , ona prema zadanim postavkama mora prikazivati ​​status Nije konfigurirano . ^{(Not Configured )}Dvaput^(Double) kliknite na istu postavku da biste je promijenili:

This policy setting determines the percentage of connection bandwidth that the system can reserve. This value limits the combined bandwidth reservations of all programs running on the system. By default, the Packet Scheduler limits the system to 80 percent of the bandwidth of a connection, but you can use this setting to override the default. If you enable this setting, you can use the “Bandwidth limit” box to adjust the amount of bandwidth the system can reserve. If you disable this setting or do not configure it, the system uses the default value of 80 percent of the connection. If a bandwidth limit is set for a particular network adapter in the registry, this setting is ignored when configuring that network adapter.

4. Sada, u gore prikazanom prozoru, odaberite Omogućeno^(Enabled) i u odjeljku Opcije^(Options) ; možete unijeti postotak za ograničavanje propusnosti. Ako ovdje unesete 0 posto^{(0 percent)} , možete dobiti rezerviranu propusnost koju rezervira sustav. AŽURIRANJE^(UPDATE) : Pročitajte bilješku u nastavku.

Kliknite Primijeni^(Apply) , a zatim U redu^(OK) . Sada možete zatvoriti uređivač lokalnih grupnih pravila^{(Local Group Policy Editor)} i ponovno pokrenuti sustav s dobivenom propusnošću.

Ako se vaša verzija sustava Windows ne isporučuje s Gpedit-om^(Gpedit) , možete otvoriti Regedit i otići do sljedećeg ključa registra:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched

Dajte mu Vrijednost podataka 0 . Ako Psched ne postoji, kreirajte ga.

Hope you find the tip useful!

NAPOMENA ADMIN-a objavljena 09. siječnja 2014.:^{(NOTE BY ADMIN posted on 09 Jan 2014:)}

Tvrdnja da Windows uvijek^(always) rezervira postotak dostupne propusnosti za QoS je netočna. Sto posto propusnosti mreže dostupno je za dijeljenje svim programima osim ako^(unless) program izričito zahtijeva prioritetnu propusnost. Ova "rezervirana" propusnost i dalje je dostupna drugim programima osim ako program koji traži podatke ne šalje. Ako program koji je rezervirao propusnost ne šalje dovoljno podataka za korištenje, neiskorišteni dio rezervirane propusnosti dostupan je^{(is available)} za druge tokove podataka na istom hostu, kaže KB316666 .

Dakle, što će se dogoditi ako promijenite ograničenje rezervirane propusnosti na nulu?^{(So what will happen if you change the limit of the reservable bandwidth to zero?)}

Evo što Microsoft ima za reći^{(to say)} :

Operativni sustav Windows^{(Windows Operating System)} rezervira fiksni postotak ukupne internetske^(Internet) propusnosti za korištenje QoS-a ili kvalitete usluge ^(Service)kao^(QoS) što je^(Quality) ažuriranje sustava Windows , obnova licence, itd. Dakle, kada ograničite propusnost^(Bandwidth) za rezerviranje operativnog sustava na 0, to će utjecati na rad aktivnosti sustava poput automatskog ažuriranja sustava Windows^{(this will affect the operating system activities like Automatic Windows Updates)} . Ako QoS-svjesna^(QoS-aware) aplikacija rezervira više propusnosti nego što koristi, tada je neiskorištena, rezervirana propusnost dostupna za korištenje drugim aplikacijama. Rezervacija ne osigurava da će širina pojasa biti dostupna QoS-aware- u^(QoS-aware)aplikacija jer aplikacije koje nisu svjesne QoS-^(QoS-aware) a mogu potrošiti previše propusnosti.

Limit Reservable Bandwidth Setting in Windows 11/10

In general, bandwidth iѕ the rate at which dаta travels to and fro from your computer. In other words, bandwidth is the range coverеd for data transmisѕion between an upper range and a lower range. Bandwidth is usually controlled by your Internet Service Provider (ISP). However, there exist some settings in Windows, by configuring which you limit the reservable bandwidth for your system.

Primarily, Windows reserves a certain amount of bandwidth for its application requirements and operation purposes. By configuring its setting in the Group Policy, you can easily limit the reservable bandwidth. This article will show you stepwise, how to access or open up the reservable bandwidth on your Windows 11/10/8.

Limit Reservable Bandwidth Setting in Windows 11/10

1. Press Windows Key + R combination, type put gpedit.msc in Run dialog box and hit Enter to open the Local Group Policy Editor. The Group Policy Editor, incidentally, is not available in Windows Home version. It is available only in Windows Pro, Enterprise, etc., versions,

2. Navigate here:

Computer Configuration -> Administrative -> Network -> Qos Packet Scheduler

3. In the right pane of this window, look for the settings named Limit reservable bandwidth, it must be showing a Not Configured status by default. Double click on the same setting to modify it:

This policy setting determines the percentage of connection bandwidth that the system can reserve. This value limits the combined bandwidth reservations of all programs running on the system. By default, the Packet Scheduler limits the system to 80 percent of the bandwidth of a connection, but you can use this setting to override the default. If you enable this setting, you can use the “Bandwidth limit” box to adjust the amount of bandwidth the system can reserve. If you disable this setting or do not configure it, the system uses the default value of 80 percent of the connection. If a bandwidth limit is set for a particular network adapter in the registry, this setting is ignored when configuring that network adapter.

4. Now, in the above-shown window, select Enabled and in the Options section; you could input the percentage for limiting the bandwidth. If you input 0 percent here, you can gain the reserved bandwidth reserved by the system. UPDATE: Do read the note below.

Click Apply, followed by OK then. You may now close the Local Group Policy Editor and reboot the system with gained bandwidth.

If your version of Windows does not ship with Gpedit, then you may open Regedit and navigate to the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Psched

Give it Value Data 0. If Psched does not exist, create it.

Hope you find the tip useful!

NOTE BY ADMIN posted on 09 Jan 2014:

The claim that Windows always reserves a percentage of the available bandwidth for QoS is incorrect. One hundred percent of the network bandwidth is available to be shared by all programs unless a program specifically requests priority bandwidth. This “reserved” bandwidth is still available to other programs unless the requesting program is sending data. If the program that reserved the bandwidth is not sending sufficient data to use it, the unused part of the reserved bandwidth is available for other data flows on the same host, says KB316666.

So what will happen if you change the limit of the reservable bandwidth to zero?

Here is what Microsoft has to say:

The Windows Operating System reserves a fixed percentage of the total Internet bandwidth for the QoS or Quality of Service usage like Windows update, license renewal, etc. Thus, when you limit the Reservable Bandwidth of the operating system to 0, this will affect the operating system activities like Automatic Windows Updates. If a QoS-aware application reserves more bandwidth than it uses, then the unused, reserved bandwidth is available for use by other applications. The reservation does not ensure that the bandwidth will be available to the QoS-aware application because applications that are not QoS-aware might consume too much bandwidth.
