Windows自身没有提供类似Linux cgroup的能力来限制进程或进程组的资源占用,进程CPU/IO/内存/网络等资源的控制只能由自己实现。目前已有第三方的实现,主要是限制进程CPU的占用,如文档 < 21 Best Ways to Limit the CPU Usage of a Process > 所描述的BES,Process Tamer等软件。自Windows 8及Server 2012开始Windows系统有提供以job为单位的CPU占用及内存上限设置,之前的版本则只能以进程或线程为单位进行限制。
进程CPU占用限制方案
即时轮询系统所有进程(线程)的CPU占用,当发现所设定进程有超标时强制暂停进程所有线程的执行,然后在适当的时机再恢复执行。其中所涉及技术点:
进程CPU占用查询 GetProcessTimes
BOOL GetProcessTimes(
[in] HANDLE hProcess,
[out] LPFILETIME lpCreationTime,
[out] LPFILETIME lpExitTime,
[out] LPFILETIME lpKernelTime,
[out] LPFILETIME lpUserTime
);
此函数可以获取进程从创建至当前的总运行时间及总的CPU时间,(KernelTime + UserTime) < 系统CPU数 * (当前时间 - CreationTime)
线程CPU占用查询 GetThreadTimes
BOOL GetThreadTimes(
[in] HANDLE hThread,
[out] LPFILETIME lpCreationTime,
[out] LPFILETIME lpExitTime,
[out] LPFILETIME lpKernelTime,
[out] LPFILETIME lpUserTime
);
QueryThreadCycleTime可以提供更精准的CPU时间数据,单位为CPU时钟周期
BOOL QueryThreadCycleTime(
[in] HANDLE ThreadHandle,
[out] PULONG64 CycleTime
);
线程暂停及恢复
Windows平台没有提供暂停整个进程的支持函数,只能以线程为单位来操作,即SuspendThread及ResumeThread:
DWORD SuspendThread(
[in] HANDLE hThread
);
DWORD ResumeThread(
[in] HANDLE hThread
);
CPU亲和性设置: SetProcessAffinityMask
BOOL SetProcessAffinityMask(
[in] HANDLE hProcess,
[in] DWORD_PTR dwProcessAffinityMask
);
此函数可以限定进程及其所有线程所能使用的CPU,故一定程序上亦限定了进程最大的系统CPU占用率。
DWORD_PTR SetThreadAffinityMask(
[in] HANDLE hThread,
[in] DWORD_PTR dwThreadAffinityMask
);
此函数可单独限制特定线程的CPU亲和性。
进程优先级设置: SetPriorityClass
优先级解决的是优先运行及退让CPU的问题,本质上并不能限定CPU占用,只是优先级高于当前任务的忙碌的时候,当前进程会主动退让CPU 线程优先级设置:SetThreadPriority
BOOL SetThreadPriority(
[in] HANDLE hThread,
[in] int nPriority
);
Job Objects
Windows系统提供了Job的概念用以管理多个进程,可以限制Job对象内所有进程及期线程的CPU核心占用、CPU占用及内存分配上限等,均通过SetInformationJobObject来实现,具体的CPU限制由JOBOBJECT_CPU_RATE_CONTROL_INFORMATION管理,内存限制则由JOBOBJECT_EXTENDED_LIMIT_INFORMATION来管理。
BOOL SetInformationJobObject(
[in] HANDLE hJob,
[in] JOBOBJECTINFOCLASS JobObjectInformationClass,
[in] LPVOID lpJobObjectInformation,
[in] DWORD cbJobObjectInformationLength
);
需要注意的是CPU占用设置只有Windows 8及Server 2012之后的版本有效。
CPU Sets
此部分只限定了CPU Affinity属性
实验验证
可以直接利用开源项目go-winjob验证,验证系统Windows 8 x64,go-winjob git repo: https://github.com/kolesnikovae/go-winjob
验证程序
#include <stdio.h>
#include <stdlib.h>
void main(int argc, char *argv[])
{
unsigned long total = 0, count = 0, i = 0;
while (1) {
if (malloc(1024)) {
total += 1024;
count++;
}
if (!(++i & 4095))
printf("alloc: %u size: %u bytes\n", count, total);
}
}
无限制
在无限制的情况下,此进程会占满一个CPU核心,commit内存总占用达2G

单一进程
在设定CPU上限16%及内存16M上限之后,结果如下:
examples/job_object.go按如下修改:
var limits = []winjob.Limit{
winjob.WithBreakawayOK(),
winjob.WithKillOnJobClose(),
winjob.WithActiveProcessLimit(3),
winjob.WithProcessTimeLimit(10 * time.Second),
winjob.WithCPUHardCapLimit(1600), // 16%
winjob.WithProcessMemoryLimit(16 << 20), // 16MB
winjob.WithWriteClipboardLimit(),
}
const defaultCommand = ".\\CPUStress.exe"
多进程(双进程)
将winjob.WithProcessMemoryLimit 改为 winjob.WithJobMemoryLimit,后者表示此job内所有进程要占用的总内存限制:
var limits = []winjob.Limit{
winjob.WithBreakawayOK(),
winjob.WithKillOnJobClose(),
winjob.WithActiveProcessLimit(3),
winjob.WithProcessTimeLimit(10 * time.Second),
winjob.WithCPUHardCapLimit(1600), // 16%
winjob.WithJobMemoryLimit(16 << 20), // 16MB
winjob.WithWriteClipboardLimit(),
}
验证结果如下:

winjob example代码:
// +build windows
package main
import (
"encoding/json"
"log"
"os"
"os/exec"
"os/signal"
"time"
"golang.org/x/sys/windows"
"github.com/kolesnikovae/go-winjob"
)
var limits = []winjob.Limit{
winjob.WithBreakawayOK(),
winjob.WithKillOnJobClose(),
winjob.WithActiveProcessLimit(3),
winjob.WithProcessTimeLimit(10 * time.Second),
winjob.WithCPUHardCapLimit(1600), // 16%
winjob.WithJobMemoryLimit(16 << 20), // 16MB
winjob.WithWriteClipboardLimit(),
}
const defaultCommand = ".\\CPUStress.exe"
const stressCommand = ".\\CPUStressX64.exe"
func main() {
job, err := winjob.Create("", limits...)
if err != nil {
log.Fatalf("Create: %v", err)
}
cmd := exec.Command(defaultCommand)
cmd.Stderr = os.Stderr
cmd.SysProcAttr = &windows.SysProcAttr{

CreationFlags: windows.CREATE_SUSPENDED,
}
if err := stress.Start(); err != nil {
log.Fatalf("Start: %v", err)
}
s := make(chan os.Signal, 1)
signal.Notify(s, os.Interrupt)
c := make(chan winjob.Notification)
subscription, err := winjob.Notify(c, job)
if err != nil {
log.Fatalf("Notify: %v", err)
}
done := make(chan struct{})
go func() {
defer close(done)
ticker := time.NewTicker(time.Second * 5)
defer ticker.Stop()
var counters winjob.Counters
for {
select {
case <-s:
log.Println("Closing job object")
if err := job.Close(); err != nil {
log.Fatal(err)
}
log.Println("Closing subscription")
if err := subscription.Close(); err != nil {
log.Fatal(err)
}
return
case n, ok := <-c:
if ok {
log.Printf("Notification: %#v\n", n)
} else if err := subscription.Err(); err != nil {
log.Fatalf("Subscription: %v", err)
}
case <-ticker.C:
if err := job.QueryCounters(&counters); err != nil {
log.Fatalf("QueryCounters: %v", err)
}
b, err := json.MarshalIndent(counters, "", "\t")
if err != nil {
log.Fatal(err)
}
log.Printf("Counters: \n%s\n", b)
}
}
}()
if err := job.Assign(cmd.Process); err != nil {
log.Fatalf("Assign: %v", err)
}
if err := winjob.Resume(cmd); err != nil {
log.Fatalf("Resume: %v", err)
}
if err := job.Assign(stress.Process); err != nil {
log.Fatalf("Assign: %v", err)
}
if err := winjob.Resume(stress); err != nil {
log.Fatalf("Resume: %v", err)
}
if err := cmd.Wait(); err != nil {
log.Fatalf("Wait: %v", err)
}
if err := stress.Wait(); err != nil {
log.Fatalf("Wait: %v", err)
}
// Wait for a signal.

Современный мир высоких технологий предлагает большое разнообразие вариантов регистрации доменных имен. Среди популярных сочетаний выделяется простая и выразительная комбинация `slon1`. Именно такая последовательность стала основой множества доменных адресов, привлекающих внимание пользователей. Простота восприятия делает её идеальной для брендов и веб-ресурсов различного назначения.
[url=slon10t.cc]slon6.cc[/url]
Одним из интересных направлений стало использование национального домена верхнего уровня (.cc). Таким образом появилось популярное сочетание **slon1.cc**, которое сочетает простую и доступную ассоциацию со словом «слон» и одновременно обозначает принадлежность ресурса к определённой географической зоне. Такое решение способствует быстрому восприятию и идентификации сайта пользователями.
[url=slon10t.cc]slon3.at[/url]
Еще одним вариантом стал вариант **slon1.at**, в котором подчеркнута связь с австрийским сегментом сети Интернет. Такой выбор тоже имеет свою специфику и добавляет дополнительные смыслы в восприятие бренда. Благодаря своим уникальным характеристикам этот тип домена активно используется компаниями, ориентированными на европейский рынок.
[url=slon3t.cc]slon2.to[/url]
Часто владельцы ресурсов выбирают и сокращённую форму записи своего имени. К примеру, такое написание, как **slon1cc**, придаёт сайту дополнительный шарм и облегчает процесс запоминания. Подобная форма часто встречается в международной практике брендирования и отражает общую тенденцию упрощения структуры именования.
[url=slon2t.cc]slon3.at[/url]
В заключение отметим ещё одну разновидность написания домена — **slon1сс**. Здесь упор сделан на двойное повторение буквы «с», что создаёт особое звучание и запоминающийся эффект. Такая игра букв усиливает привлекательность домена и выделяет ресурс среди прочих аналогичных предложений.

Pope Leo XIV celebrated the first Christmas since his election by denouncing the suffering of people of Gaza – taking shelter in tents from the “rain, wind and cold” – and by calling for the guns to fall silent in Ukraine.
[url=https://mellstroycomcasino.com]мелстрой ссылка[/url]
On Christmas Day, the first US-born pope, offered the traditional “Urbi et Orbi” blessing (“To the City and to the World”) from the balcony of St Peter’s, surveying a world speckled with conflicts from Yemen to Myanmar, and calling for compassion towards those who have fled their homelands to seek a future in Europe and America.
[url=https://mellstroy5.com]мелстрой казино ссылка[/url]
Leo, who was elected on May 8, said Thursday that Jesus Christ is “our peace” because he “shows us the way to overcome conflicts, whether interpersonal or international. With his grace, we can and must each day our part to reject hatred, violence and opposition, and to practice dialogue, peace and reconciliation.”
[url=https://mellstream.com]mellstroy com[/url]
The pontiff began by asking for “justice, peace and stability” for Lebanon, the Palestinian territories, Israel and Syria. Later, he said that, by becoming man, “Jesus took upon himself our fragility,” allowing him to identify “with those who have nothing left and have lost everything, like the inhabitants of Gaza.”

The pope’s first Christmas since his election took place in wet and cold conditions, but that failed to deter large crowds from coming out to hear his message.
Earlier during Mass, he asked how, at Christmas, “can we not think of the tents in Gaza, exposed for weeks to rain, wind and cold.” With more than 400,000 homes destroyed during Israel’s war against Hamas, Gazans are being forced to choose this winter between living in tents exposed to the elements or living inside buildings that could collapse any minute.
“Fragile is the flesh of defenseless populations, tried by so many wars, ongoing or concluded, leaving behind rubble and open wounds,” Leo said. He quoted an Israeli poet, Yehuda Amichai, who called for peace to blossom “like wildflowers.”

Christmas celebrated once again in Bethlehem but West Bank suffering persists
Later during his Christmas message, he called for compassion towards those “who are fleeing their homeland to seek a future elsewhere, like the many refugees and migrants who cross the Mediterranean or traverse the American continent.” He offered Christmas greetings in different languages including Italian, English, Arabic, Chinese, Polish.
Since his election, Leo has highlighted the plight of those suffering of those in Gaza, and has been outspoken by calling for the better treatment of migrants. In his first major interview in September, the American pope voiced concern over “some things” happening in the country of his birth, highlighting the significance of a letter his predecessor, Pope Francis, had sent to US bishops earlier this year, rebuking the administration’s deportation plans.
