Ускорьте ответ nginx

Я использую nginx + uwsgi + Django для запуска моей службы.

Соответствующая конфигурация показана ниже:

uwsgi config

[uwsgi]
pythonpath=/path/to/pythonpath
chdir=/path/to/chdir
env=DJANGO_SETTINGS_MODULE=conf.settings
module=moudle.wsgi
master=True
pidfile=logs/pidfile.pid
vacuum=True
max-requests=1000
enable-threads=true
processes = 4
threads=8
listen=1024
daemonize=logs/wsgi.log
http=0.0.0.0:10205
buffer-size=32000
socket-timeout=1500
harakiri=1500
http-timeout=1500

nginx config

nginx.conf

worker_processes  12;

events {
    use epoll;
    worker_connections  65535;
}


http {
    include       mime.types;
    include       log_format.conf;
    include       upstream.conf;
    default_type  application/octet-stream;

    sendfile        on;
    tcp_nopush     on;

    keepalive_timeout  1800;
    server_tokens off;

    client_max_body_size 100m;
    gzip  on;
    gzip_min_length 1k;
    gzip_buffers 4 16k;
    gzip_comp_level 5;
    gzip_types text/plain application/json application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
    gzip_vary off;
    include "site-enabled/*.conf";
    proxy_buffering on;
    proxy_buffer_size 4k;
    proxy_buffers 8 1M;
    proxy_busy_buffers_size 2M;
    proxy_max_temp_file_size 0;
}

log_format.conf

log_format upstream '$remote_addr - $host [$time_local] "$request" '
                    '$status $body_bytes_sent $request_time $upstream_response_time '
                    '"$http_user_agent" "$http_x_forwarded_for" ';

upstream.conf

upstream my_service {
        server host:16020  weight=50;
        server host:16020  weight=50;
        keepalive 100;
}

site-enabled/my_service.conf

server {
    listen 7020;
    server_name  my-service.xxx.cn;
    client_max_body_size 100M;
    access_log  logs/my_service_access.log  upstream;
    root /path/to/my_service/dist;

    location ^~ /api/base_api {
        proxy_redirect off;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_read_timeout 90;
        proxy_pass http://my_service;
        uwsgi_buffering  on;
        uwsgi_buffers    8 8k;
        uwsgi_buffer_size  8k;
    }

    location / {
        try_files $uri /index.html =404;
    }
}

Когда я делаю запрос, ответ возвращается от uwsgi почти через 0,5 с.

[pid: 8841|app: 0|req: 4390/12492] xxx.xxx.xxx.xxx () {44 vars in 1103 bytes} [Thu Aug  4 14:13:23 2022] GET /api/account_opening_review/aor?page_size=1000 => generated 1668926 bytes in 499 msecs (HTTP/1.0 200) 4 headers in 119 bytes (1 switches on core 3)

Но я получил 504 Gateway Time-out ошибку с приведенным ниже журналом запросов nginx

xxx.xxx.xxx.xxx - host [04/Aug/2022:14:25:05 +0800] "GET /api/account_opening_review/aor?page_size=1000 HTTP/1.1" 499 0 60.000 60.000 "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/103.0.0.0 Safari/537.36" "xxx.xxx.xxx.xxx"

Может ли кто-нибудь сказать мне, почему появляется эта ошибка, и есть ли способ ускорить ответ nginx?

Спасибо!
