According to Varnish documentation, “A purge is what happens when you pick out an object from the cache and discard it along with its variants.” A Varnish purge is very similar to a Magento cache clean command (or clicking Flush Magento Cache in the Magento Admin).

In fact, as discussed in this section, when you clean, flush, or refresh the Magento cache, Varnish purges as well.

Configure Magento to purge Varnish

execute this code 

bin/magento setup:config:set --http-cache-hosts=192.0.2.100,192.0.2.155:6081

If you want to see the total loaded time for any page to compare the time between the first and second time you can use this command 

curl -L --output /dev/null --silent --show-error --write-out 'lookup:        %{time_namelookup}\nconnect:    %{time_connect}\nappconnect:    %{time_appconnect}\npretransfer:   %{time_pretransfer}\nredirect:      %{time_redirect}\nstarttransfer: %{time_starttransfer}\ntotal:      %{time_total}\n' 'https://www.example.com/'

you need to increase the memory_limit in php.ini

and as a quick solution you can use these commands directly in the command line

php -dmemory_limit=5G bin/magento setup:di:compile

and 

php -dmemory_limit=5G bin/magento setup:static-content:deploy

another code for the composer update

php -dmemory_limit=5G composer.phar update

php -d memory_limit=-1 /usr/local/bin/composer update

We will show here how we can display a private content in a full cached page, it is very useful if you want to display information per customer
