Настройка производительности Apache для высокого трафика с помощью MPM Event или MPM Prefork? ⇐ Php

[Anonymous]

Привет, я хочу немного настроить свой новый сервер, я тестировал с помощью mpm_prefork и mpm_event и не заметил больших различий..Может быть, я неправильно настроил?
Сервер:
Ampere® Altra® Q80-30ЦП 80 ядер / 80 потоков @ 3 Генерация ГГц:
Altra RAM 128 ГБ ECC DDR4 RAMDrives
2 твердотельных накопителя NVMe емкостью 960 ГБ > Центр обработки данных
Я пробовал с помощью mpm_prefork.conf:
StartServers 80
MinSpareServers 80
MaxSpareServers 160
MaxRequestWorkers 2048
MaxConnectionsPerChild 10000

И результаты:


Server Software: Apache/2.4.62
Server Hostname: domain.ro
Server Port: 443
SSL/TLS Protocol: TLSv1.3,TLS_AES_256_GCM_SHA384,256,256
Server Temp Key: X25519 253 bits
TLS Server Name: domain.ro

Document Path: /?test

Concurrency Level: 100

Complete requests: 10000
Failed requests: 820

90% 1532
95% 1619
98% 1729
99% 1805
100% 2519 (longest request)

Затем я установил mpm_event.conf:
StartServers 20
MinSpareThreads 25
MaxSpareThreads 90
ThreadLimit 128
MaxRequestWorkers 1500
ServerLimit 2000

И www.conf
pm.max_children = 2000

; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: (min_spare_servers + max_spare_servers) / 2
pm.start_servers = 200

; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 5

; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 300

; The number of rate to spawn child processes at once.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
; Default Value: 32
;pm.max_spawn_rate = 32

; The number of seconds after which an idle process will be killed.
; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
pm.max_requests = 500
