Der Inhalt dieses Artikels befasst sich mit dem Vergleich zwischen dem Swoole-Synchronisationsmodus und dem Coroutine-Modus. Er hat einen gewissen Referenzwert. Ich hoffe, er wird für Sie hilfreich sein.
In der modernen fortgeschrittenen PHP-Entwicklung bringt Swoole PHP mehr Möglichkeiten, wie zum Beispiel: residenter Speicher, Coroutinen und der große Unterschied zwischen dem traditionellen Apache/FPM-Modus und dem residenten Speichermodus (Synchronisation), den ich gemacht habe Tests durchgeführt, und jeder kann intuitiv die enorme Leistungsverbesserung spüren, aber wie viel Leistungsverbesserung wurde nach der Einführung der Coroutine gebracht? Welche Leistungsaspekte werden verbessert? Lassen Sie es uns Schritt für Schritt testen.
Testartikel zum traditionellen Apache/FPM-Modus und zum residenten Speichermodus (Synchronisation):
Umfassender Vergleichstest der MixPHP-Parallelitätsleistung
Vergleich zwischen Coroutine-Modus und Resident-Memory-Modus (synchron)/traditioneller Modus:
Resident-Modus/traditioneller Modus sind beide synchrone Blockierungsprogrammierung, da im gleichen Prozess keine Anforderungen verarbeitet werden können Parallel, um die Parallelität zu verbessern, können daher nur mehr Prozesse geöffnet werden, normalerweise mehr als 100
oder sogar mehr. Jeder Prozess hat einen grundlegenden Speicherverbrauch, der sich zu einer Menge summiert und durch den gesamten Linux-Prozess begrenzt wird Bei einer großen Anzahl von Prozessen kann die Gesamtzahl der Parallelität nicht überschritten werden, was natürlich zu einer großen Leistungsverschwendung im Vergleich zum herkömmlichen FPM-Modus führt Von Grund auf ist der Resident-Modus immer noch viel besser, aber Coroutinen sind offensichtlich besser.
Ausführungsmethode des Coroutine-Modus:
Im Coroutine-Modus kann ein Prozess N Anforderungen gleichzeitig ausführen, aber nur eine davon wird gleichzeitig ausgeführt Das heißt, bei der Ausführung auf Clients wie MySQL/Redis wartet der residente Modus/traditionelle Modus aufgrund der Notwendigkeit, auf die Antwort des Clients zu warten, normalerweise auf die Antwort, und die Coroutine unterbricht die aktuelle Coroutine Zu diesem Zeitpunkt werden andere Anforderungen in anderen Coroutinen verarbeitet, sodass die Coroutine N Anforderungen gleichzeitig verarbeiten kann. Verglichen mit der Erhöhung des Speicherverbrauchs eines Prozesses ist dies offensichtlich viel weniger, da die Coroutine parallel verarbeiten kann, sodass Sie normalerweise nur die Anzahl der Prozesse konfigurieren müssen, die etwa dem 1- bis 2-fachen der Anzahl der CPUs entspricht. Weniger Prozesse führen zu weniger CPU-Thread-Wechsel und reduzieren viele Leistungsverluste.
MixPHP ist ein leistungsstarkes PHP-Framework, das auf Swooles Drei-Modus-FPM, residentem Speicher und Coroutine-Modus basiert können leicht praktische Testergebnisse sein.
Testumgebung:
Docker-Container, begrenzt auf 1 CPU.
Andere Parameter lauten wie folgt:
Server Name: mix-httpd Framework Version: 1.1.0-RC PHP Version: 7.2.9 Swoole Version: 4.1.0 Listen Addr: 127.0.0.1 Listen Port: 9501
Code:
Simulieren Sie allgemeine HTTP-Entwicklungsanforderungen und führen Sie drei SQL-Anfragen aus.
// 默认动作 public function actionIndex() { PDO::createCommand("select * from `test` where id = 1")->queryOne(); PDO::createCommand("select * from `test` where id = 2")->queryOne(); return PDO::createCommand("select * from `test` limit 5")->queryAll(); }
Residenter Speichermodus (synchron):

8 | 500 | 688.56 |
50 | 100 | 770.69 |
50 | 300 | 304.90 |
50 | 300 | 378.95 |
Coroutine-Modus:
进程数 | 并发数 | RPS |
---|---|---|
8 | 100 | 834.12 |
8 | 300 | 837.50 |
8 | 500 | 824.14 |
协程在本次测试中并没有像之前的传统 Apache/FPM 模式与常驻内存模式(同步)的测试一样展现出巨大的性能提升,说明:
在少量能快速响应的 SQL 请求中,协程的提升并不明显,应该要在响应时间更大时,才能感受到协程优势。
常驻内存模式的进程数配置过多,并发性能反而会降低,该问题同样适用于传统 Apache/FPM 模式。

对比 8 个进程时的结果,并发量降低非常明显,看来进程数过多并不能提升性能,反而会降低性能。
