Good evening, my site is https://www.emporiobit.com.br it is not yet in production.
I use magento 2.2.5 with varnish and redis
I configured 4G for Varnish and 4G for php memory_limit, my VPS has 12gb ram
When I open the site there is a slow but when the site is open it loads everything at once, I believe because of the cache
The ping from Brazil where my public is located until the server is around 220~290ms, using cloudflare is around 130~140ms
I took a test at www.webpagetest.org and the TTFB scored 2,502s, I think it's a bit high
Could you help me sort out how slow to open?
Report site webpagetest

  • your first bit response time it 2.502 second means your application has some issue for this reason,it is taking at time

  • 2,502s basically says "cache me". How did you configure Varnish? Have you selected "Varnish Cache" in admin settings? Have you applied the Varnish software to the server and Magento VCL file for it? Finally, make sure that you have enabled caches via bin/magento cache:enable Aug 30, 2018 at 7:52
  • @AmitBera The TTFB is high, how to diagnose to achieve a better performance? I generated a report in csv of the magento profile but I could not find out where the problem is Aug 30, 2018 at 17:40
  • @DanielV.varnish is running with 4G ram and as for vcl I exported it from console admin magento2 Aug 30, 2018 at 17:45

You can follow some steps below :

  • Merge Css
  • Merge javascript
  • Put store to production mode
  • Enable all cache

Then check speed of your store

Good luck !

  • Hi, all these procedures were done. Aug 30, 2018 at 4:06
  • Your store still slow or speed up ? Aug 30, 2018 at 7:18

All related items are OK except for PHP-FPM that I do not have installed. With this php-fpm is there performance gain?

  • yes and no, you need to test it, probably you have some issues with php code in your templates

Use the latest Magento 2.2* supports php 7.1 or not. Please below link Refere and check PHP 7.1 Support or not.

==> http://devdocs.magento.com/guides/v2.2/install-gde/prereq/php-ubuntu.html

==> After It it is supported then you install this PHP plugin.

sudo apt-get install php7.1 php7.1-xml php7.1-dom php7.1-intl php7.1-imap

==> If you running multiple PHP versions set 7.1 to the as default Using this command.

==> sudo update-alternatives --set php /usr/bin/php7.1

Set to Developer Mode php -f bin/magento deploy:mode:show

php -f bin/magento deploy:mode:set developer

==> Check Magento cache is enabled Or not It's FPC Not Enabled please enabled FPC cache. Then check cache status.

php -f bin/magento cache:status

If it is not enabled (cache status of 1's)

php -f bin/magento cache:enable

then you will Enable JS/CSS bundling

Stores -> Configuration -> Advanced -> Developer

==> Template Configuration

Minify HTML ==> set to Yes Javascript Settings

Merge JS files ==> set to Yes

Enable JS Bundling ==> set to Yes

Minify JS files ==> set to Yes

CSS Configuration

        'backend_options' => 
        array (
          'server' => '',
          'database' => '0',
          'port' => '6379',
      'page_cache' => 
      array (
        'backend' => 'Cm_Cache_Backend_Redis',
        'backend_options' => 
        array (
          'server' => '',
          'port' => '6379',
          'database' => '1',
          'compress_data' => '0',
