Slow Content Download [Apache Nginx PHP-fpm]

Recently I migrated from hestia apache2 nginx server to apache2 nginx php-fpm server. Everything seems ok but i’ve noticed slow content download for documents.

At first stage server returns part of html. After a while it returns the rest.

I have an assumption fastcgi_finish_request is the cause of the problem. I’ve tried to disable fastcgi cache for wp-admin via code below. But it seems function fastcgi_finish_request still exists.

Probably it’s not related to fastcgi_finish_request.

location / {
		proxy_pass https://209.124.84.135:8443;

        if ($request_uri ~* "/wp-admin/*") {
           set $no_cache 1;
        }

		location ~* ^.+\.(css|htm|html|js|json|xml|apng|avif|bmp|cur|gif|ico|jfif|jpg|jpeg|pjp|pjpeg|png|svg|tif|tiff|webp|aac|caf|flac|m4a|midi|mp3|ogg|opus|wav|3gp|av1|avi|m4v|mkv|mov|mpg|mpeg|mp4|mp4v|webm|otf|ttf|woff|woff2|doc|docx|odf|odp|ods|odt|pdf|ppt|pptx|rtf|txt|xls|xlsx|7z|bz2|gz|rar|tar|tgz|zip|apk|appx|bin|dmg|exe|img|iso|jar|msi|webmanifest)$ {
			try_files  $uri @fallback;

			root       xxx;
			access_log xxx;
			access_log xxx;

			expires    10800;
		}
	}

What could be the cause of this problem?

I’ve tried to increase some values at nginx.conf.

	proxy_buffers                   256 4k;
	proxy_buffer_size               32k;
	proxy_busy_buffers_size         32k;

to

    proxy_buffers                   1024 4k;
	proxy_buffer_size               128k;
	proxy_busy_buffers_size         128k;

Now page loads completely in 20 seconds with low Content download time.

But it’s strange why page do not load completely in 12 seconds if we have some html at the beginning with previous settings.
